Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux kernel for openSUSE 11.2 was updated to 2.6.31.8 to fix the following bugs and security issues :

  - A file overwrite issue on the ext4 filesystem could be     used by local attackers that have write access to a     filesystem to change/overwrite files of other users,     including root. (CVE-2009-4131)

  - A remote denial of service by sending overly long     packets could be used by remote attackers to crash a     machine. (CVE-2009-1298)

  - The mac80211 subsystem in the Linux kernel allows remote     attackers to cause a denial of service (panic) via a     crafted Delete Block ACK (aka DELBA) packet, related to     an erroneous 'code shuffling patch.' (CVE-2009-4026)

  - Race condition in the mac80211 subsystem in the Linux     kernel allows remote attackers to cause a denial of     service (system crash) via a Delete Block ACK (aka     DELBA) packet that triggers a certain state change in     the absence of an aggregation session. (CVE-2009-4027)

  - The poll_mode_io file for the megaraid_sas driver in     the Linux kernel has world-writable permissions, which     allows local users to change the I/O mode of the driver     by modifying this file. (CVE-2009-3939)

  - The collect_rx_frame function in     drivers/isdn/hisax/hfc_usb.c in the Linux kernel allows     attackers to have an unspecified impact via a crafted     HDLC packet that arrives over ISDN and triggers a buffer     under-read. This requires the attacker to access the     machine on ISDN protocol level. (CVE-2009-4005)

  - Array index error in the gdth_read_event function in     drivers/scsi/gdth.c in the Linux kernel allows local     users to cause a denial of service or possibly gain     privileges via a negative event index in an IOCTL     request. (CVE-2009-3080)

  - The get_instantiation_keyring function in     security/keys/keyctl.c in the KEYS subsystem in the     Linux kernel does not properly maintain the reference     count of a keyring, which allows local users to gain     privileges or cause a denial of service (OOPS) via     vectors involving calls to this function without     specifying a keyring by ID, as demonstrated by a series     of keyctl request2 and keyctl list commands.
    (CVE-2009-3624)

  - The fuse_direct_io function in fs/fuse/file.c in the     fuse subsystem in the Linux kernel might allow attackers     to cause a denial of service (invalid pointer     dereference and OOPS) via vectors possibly related to a     memory-consumption attack. (CVE-2009-4021)

  - Multiple race conditions in fs/pipe.c in the Linux     kernel allow local users to cause a denial of service     (NULL pointer dereference and system crash) or gain     privileges by attempting to open an anonymous pipe via a     /proc/*/fd/ pathname. As openSUSE 11.2 by default sets     mmap_min_addr protection, this issue will just Oops the     kernel and not be able to execute code. (CVE-2009-3547)

  - net/unix/af_unix.c in the Linux kernel allows local     users to cause a denial of service (system hang) by     creating an abstract-namespace AF_UNIX listening socket,     performing a shutdown operation on this socket, and then     performing a series of connect operations to this     socket. (CVE-2009-3621)

  - drivers/firewire/ohci.c in the Linux kernel when     packet-per-buffer mode is used, allows local users to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unknown other impact via     an unspecified ioctl associated with receiving an ISO     packet that contains zero in the payload-length field.
    (CVE-2009-4138)

  - The ext4_decode_error function in fs/ext4/super.c in     the ext4 filesystem in the Linux kernel allows     user-assisted remote attackers to cause a denial of     service (NULL pointer dereference), and possibly have     unspecified other impact, via a crafted read-only     filesystem that lacks a journal. (CVE-2009-4308)

  - The ext4_fill_flex_info function in fs/ext4/super.c in     the Linux kernel allows user-assisted remote attackers     to cause a denial of service (divide-by-zero error and     panic) via a malformed ext4 filesystem containing a     super block with a large FLEX_BG group size (aka     s_log_groups_per_flex value). (CVE-2009-4307)

  - Unspecified vulnerability in the EXT4_IOC_MOVE_EXT (aka     move extents) ioctl implementation in the ext4     filesystem in the Linux kernel allows local users to     cause a denial of service (filesystem corruption) via     unknown vectors, a different vulnerability than     CVE-2009-4131. (CVE-2009-4306)

  - The EXT4_IOC_MOVE_EXT (aka move extents) ioctl     implementation in the ext4 filesystem in the Linux     kernel allows local users to overwrite arbitrary files     via a crafted request, related to insufficient checks     for file permissions. This can lead to privilege     escalations. (CVE-2009-4131)

  - The rt2870 and rt2860 drivers were refreshed to the     level they are in the Linux 2.6.32 kernel, bringing new     device support and new functionality.

Indications Everyone using the Linux Kernel on x86_64 architecture should update.

Contraindications None.

Problem description

The SUSE Linux Enterprise 11 Kernel was updated to 2.6.27.42 fixing various bugs and security issues.

The following security issues were fixed :

  - A underflow in the e1000 jumbo ethernet frame handling     could be use by link-local remote attackers to crash the     machine or potentially execute code in kernel context.
    This requires the attacker to be able to send Jumbo     Frames to the target machine. (CVE-2009-4536)

  - A underflow in the e1000e jumbo ethernet frame handling     could be use by link-local remote attackers to crash the     machine or potentially execute code in kernel context.
    This requires the attacker to be able to send Jumbo     Frames to the target machine. (CVE-2009-4538)

  - drivers/firewire/ohci.c in the Linux kernel, when     packet-per-buffer mode is used, allows local users to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unknown other impact via     an unspecified ioctl associated with receiving an ISO     packet that contains zero in the payload-length field.
    (CVE-2009-4138)

  - The ext4_fill_flex_info function in fs/ext4/super.c in     the Linux kernel allows user-assisted remote attackers     to cause a denial of service (divide-by-zero error and     panic) via a malformed ext4 filesystem containing a     super block with a large FLEX_BG group size (aka     s_log_groups_per_flex value). (CVE-2009-4307)

  - The ext4_decode_error function in fs/ext4/super.c in the     ext4 filesystem in the Linux kernel before 2.6.32 allows     user-assisted remote attackers to cause a denial of     service (NULL pointer dereference), and possibly have     unspecified other impact, via a crafted read-only     filesystem that lacks a journal. (CVE-2009-4308)

  - The poll_mode_io file for the megaraid_sas driver in the     Linux kernel has world-writable permissions, which     allows local users to change the I/O mode of the driver     by modifying this file. (CVE-2009-3939)

  - The collect_rx_frame function in     drivers/isdn/hisax/hfc_usb.c in the Linux kernel allows     attackers to have an unspecified impact via a crafted     HDLC packet that arrives over ISDN and triggers a buffer     under-read. (CVE-2009-4005)

  - A negative offset in a ioctl in the GDTH RAID driver was     fixed. (CVE-2009-3080)

  - Stack-based buffer overflow in the hfs subsystem in the     Linux kernel allows remote attackers to have an     unspecified impact via a crafted Hierarchical File     System (HFS) filesystem, related to the hfs_readdir     function in fs/hfs/dir.c. (CVE-2009-4020)

Installation notes

This update is provided as a set of RPM packages that can easily be installed onto a running system by using the YaST online update module.

The openSUSE 11.1 Kernel was updated to 2.6.27.42 fixing various bugs and security issues.

CVE-2010-0622: The wake_futex_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 does not properly handle certain unlock operations for a Priority Inheritance (PI) futex, which allows local users to cause a denial of service (OOPS) and possibly have unspecified other impact via vectors involving modification of the futex value from user space.

CVE-2010-0307: The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.

CVE-2010-0410: Users could send/allocate arbitrary amounts of NETLINK_CONNECTOR messages to the kernel, causing OOM condition, killing selected processes or halting the system.

CVE-2010-0415: The do_pages_move function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service (OOPS), and possibly have unspecified other impact by specifying a node that is not part of the kernel's node set.

CVE-2010-0007: net/bridge/netfilter/ebtables.c in the ebtables module in the netfilter framework in the Linux kernel before 2.6.33-rc4 does not require the CAP_NET_ADMIN capability for setting or modifying rules, which allows local users to bypass intended access restrictions and configure arbitrary network-traffic filtering via a modified ebtables application.

CVE-2009-4536: drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel 2.6.32.3 and earlier handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload.

CVE-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets.

CVE-2010-0003: The print_fatal_signal function in kernel/signal.c in the Linux kernel before 2.6.32.4 on the i386 platform, when print-fatal-signals is enabled, allows local users to discover the contents of arbitrary memory locations by jumping to an address and then reading a log file, and might allow local users to cause a denial of service (system slowdown or crash) by jumping to an address.

CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file.

Updated kernel packages that fix multiple security issues and three bugs are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* an array index error was found in the gdth driver in the Linux kernel. A local user could send a specially crafted IOCTL request that would cause a denial of service or, possibly, privilege escalation.
(CVE-2009-3080, Important)

* a flaw was found in the collect_rx_frame() function in the HiSax ISDN driver (hfc_usb) in the Linux kernel. An attacker could use this flaw to send a specially crafted HDLC packet that could trigger a buffer out of bounds, possibly resulting in a denial of service.
(CVE-2009-4005, Important)

* permission issues were found in the megaraid_sas driver (for SAS based RAID controllers) in the Linux kernel. The 'dbg_lvl' and 'poll_mode_io' files on the sysfs file system ('/sys/') had world-writable permissions. This could allow local, unprivileged users to change the behavior of the driver. (CVE-2009-3889, CVE-2009-3939, Moderate)

* a buffer overflow flaw was found in the hfs_bnode_read() function in the HFS file system implementation in the Linux kernel. This could lead to a denial of service if a user browsed a specially crafted HFS file system, for example, by running 'ls'. (CVE-2009-4020, Low)

This update also fixes the following bugs :

* if a process was using ptrace() to trace a multi-threaded process, and that multi-threaded process dumped its core, the process performing the trace could hang in wait4(). This issue could be triggered by running 'strace -f' on a multi-threaded process that was dumping its core, resulting in the strace command hanging. (BZ#555869)

* a bug in the ptrace() implementation could have, in some cases, caused ptrace_detach() to create a zombie process if the process being traced was terminated with a SIGKILL signal. (BZ#555869)

* the RHSA-2010:0020 update resolved an issue (CVE-2009-4537) in the Realtek r8169 Ethernet driver. This update implements a better solution for that issue. Note: This is not a security regression. The original fix was complete. This update is adding the official upstream fix. (BZ#556406)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The openSUSE 11.1 Kernel was updated to 2.6.27.42 fixing various bugs and security issues.

Following security issues were fixed: CVE-2009-4536: A underflow in the e1000 jumbo ethernet frame handling could be use by link-local remote attackers to crash the machine or potentially execute code in kernel context. This requires the attacker to be able to send Jumbo Frames to the target machine.

CVE-2009-4538: A underflow in the e1000e jumbo ethernet frame handling could be use by link-local remote attackers to crash the machine or potentially execute code in kernel context. This requires the attacker to be able to send Jumbo Frames to the target machine.

CVE-2009-4138: drivers/firewire/ohci.c in the Linux kernel, when packet-per-buffer mode is used, allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unknown other impact via an unspecified ioctl associated with receiving an ISO packet that contains zero in the payload-length field.

CVE-2009-4307: The ext4_fill_flex_info function in fs/ext4/super.c in the Linux kernel allows user-assisted remote attackers to cause a denial of service (divide-by-zero error and panic) via a malformed ext4 filesystem containing a super block with a large FLEX_BG group size (aka s_log_groups_per_flex value).

CVE-2009-4308: The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference), and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal.

CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in the Linux kernel has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file.

CVE-2009-4005: The collect_rx_frame function in drivers/isdn/hisax/hfc_usb.c in the Linux kernel allows attackers to have an unspecified impact via a crafted HDLC packet that arrives over ISDN and triggers a buffer under-read.

CVE-2009-3080: A negative offset in a ioctl in the GDTH RAID driver was fixed.

CVE-2009-4020: Stack-based buffer overflow in the hfs subsystem in the Linux kernel allows remote attackers to have an unspecified impact via a crafted Hierarchical File System (HFS) filesystem, related to the hfs_readdir function in fs/hfs/dir.c.

Security fixes :

* an array index error was found in the gdth driver. A local user could send a specially crafted IOCTL request that would cause a denial of service or, possibly, privilege escalation. (CVE-2009-3080, Important)

* a flaw was found in the FUSE implementation. When a system is low on memory, fuse_put_request() could dereference an invalid pointer, possibly leading to a local denial of service or privilege escalation.
(CVE-2009-4021, Important)

* Tavis Ormandy discovered a deficiency in the fasync_helper() implementation. This could allow a local, unprivileged user to leverage a use-after-free of locked, asynchronous file descriptors to cause a denial of service or privilege escalation. (CVE-2009-4141, Important)

* the Parallels Virtuozzo Containers team reported the RHSA-2009:1243 update introduced two flaws in the routing implementation. If an attacker was able to cause a large enough number of collisions in the routing hash table (via specially crafted packets) for the emergency route flush to trigger, a deadlock could occur. Secondly, if the kernel routing cache was disabled, an uninitialized pointer would be left behind after a route lookup, leading to a kernel panic.
(CVE-2009-4272, Important)

* the RHSA-2009:0225 update introduced a rewrite attack flaw in the do_coredump() function. A local attacker able to guess the file name a process is going to dump its core to, prior to the process crashing, could use this flaw to append data to the dumped core file. This issue only affects systems that have '/proc/sys/fs/suid_dumpable' set to 2 (the default value is 0). (CVE-2006-6304, Moderate)

The fix for CVE-2006-6304 changes the expected behavior: With suid_dumpable set to 2, the core file will not be recorded if the file already exists. For example, core files will not be overwritten on subsequent crashes of processes whose core files map to the same name.

* an information leak was found in the Linux kernel. On AMD64 systems, 32-bit processes could access and read certain 64-bit registers by temporarily switching themselves to 64-bit mode. (CVE-2009-2910, Moderate)

* the RHBA-2008:0314 update introduced N_Port ID Virtualization (NPIV) support in the qla2xxx driver, resulting in two new sysfs pseudo files, '/sys/class/scsi_host/[a qla2xxx host]/vport_create' and 'vport_delete'. These two files were world-writable by default, allowing a local user to change SCSI host attributes. This flaw only affects systems using the qla2xxx driver and NPIV capable hardware.
(CVE-2009-3556, Moderate)

* permission issues were found in the megaraid_sas driver. The 'dbg_lvl' and 'poll_mode_io' files on the sysfs file system ('/sys/') had world-writable permissions. This could allow local, unprivileged users to change the behavior of the driver. (CVE-2009-3889, CVE-2009-3939, Moderate)

* a NULL pointer dereference flaw was found in the firewire-ohci driver used for OHCI compliant IEEE 1394 controllers. A local, unprivileged user with access to /dev/fw* files could issue certain IOCTL calls, causing a denial of service or privilege escalation. The FireWire modules are blacklisted by default, and if enabled, only root has access to the files noted above by default. (CVE-2009-4138, Moderate)

* a buffer overflow flaw was found in the hfs_bnode_read() function in the HFS file system implementation. This could lead to a denial of service if a user browsed a specially crafted HFS file system, for example, by running 'ls'. (CVE-2009-4020, Low)

Bug fix documentation for this update will be available shortly from www.redhat.com/docs/en-US/errata/RHSA-2010-0046/Kernel_Security_Update / index.html

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

b. ESXi userworld update for ntp

   The Network Time Protocol (NTP) is used to synchronize the time of    a computer client or server to another server or reference time    source.

   A vulnerability in ntpd could allow a remote attacker to cause a    denial of service (CPU and bandwidth consumption) by using    MODE_PRIVATE to send a spoofed (1) request or (2) response packet    that triggers a continuous exchange of MODE_PRIVATE error responses    between two NTP daemons.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-3563 to this issue.

c. Service Console package openssl updated to 0.9.8e-12.el5_4.1

   OpenSSL is a toolkit implementing SSL v2/v3 and TLS protocols with    full-strength cryptography world-wide.

   A memory leak in the zlib could allow a remote attacker to cause a    denial of service (memory consumption) via vectors that trigger    incorrect calls to the CRYPTO_cleanup_all_ex_data function.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-4355 to this issue.

   A vulnerability was discovered which may allow remote attackers to    spoof certificates by using MD2 design flaws to generate a hash    collision in less than brute-force time. NOTE: the scope of this    issue is currently limited because the amount of computation    required is still large.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-2409 to this issue.

   This update also includes security fixes that were first addressed    in version openssl-0.9.8e-12.el5.i386.rpm.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the names CVE-2009-0590, CVE-2009-1377, CVE-2009-1378,    CVE-2009-1379, CVE-2009-1386 and CVE-2009-1387 to these issues.

d. Service Console update for krb5 to 1.6.1-36.el5_4.1 and pam_krb5 to    2.2.14-15.

   Kerberos is a network authentication protocol. It is designed to    provide strong authentication for client/server applications by    using secret-key cryptography.

   Multiple integer underflows in the AES and RC4 functionality in the    crypto library could allow remote attackers to cause a denial of    service (daemon crash) or possibly execute arbitrary code by    providing ciphertext with a length that is too short to be valid.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-4212 to this issue.

   The service console package for pam_krb5 is updated to version    pam_krb5-2.2.14-15. This update fixes a flaw found in pam_krb5. In    some non-default configurations (specifically, where pam_krb5 would    be the first module to prompt for a password), a remote attacker    could use this flaw to recognize valid usernames, which would aid a    dictionary-based password guess attack.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-1384 to this issue.

e. Service Console package bind updated to 9.3.6-4.P1.el5_4.2

   BIND (Berkeley Internet Name Daemon) is by far the most widely used    Domain Name System (DNS) software on the Internet.

   A vulnerability was discovered which could allow remote attacker to    add the Authenticated Data (AD) flag to a forged NXDOMAIN response    for an existing domain.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0097 to this issue.

   A vulnerability was discovered which could allow remote attackers    to conduct DNS cache poisoning attacks by receiving a recursive    client query and sending a response that contains CNAME or DNAME    records, which do not have the intended validation before caching.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0290 to this issue.

   A vulnerability was found in the way that bind handles out-of-    bailiwick data accompanying a secure response without re-fetching    from the original source, which could allow remote attackers to    have an unspecified impact via a crafted response.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0382 to this issue.

   NOTE: ESX does not use the BIND name service daemon by default.

f. Service Console package gcc updated to 3.2.3-60

   The GNU Compiler Collection includes front ends for C, C++,    Objective-C, Fortran, Java, and Ada, as well as libraries for these    languages

   GNU Libtool's ltdl.c attempts to open .la library files in the    current working directory.  This could allow a local user to gain    privileges via a Trojan horse file.  The GNU C Compiler collection    (gcc) provided in ESX contains a statically linked version of the    vulnerable code, and is being replaced.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-3736 to this issue.

g. Service Console package gzip update to 1.3.3-15.rhel3

   gzip is a software application used for file compression

   An integer underflow in gzip's unlzw function on 64-bit platforms    may allow a remote attacker to trigger an array index error    leading to a denial of service (application crash) or possibly    execute arbitrary code via a crafted LZW compressed file.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0001 to this issue.

h. Service Console package sudo updated to 1.6.9p17-6.el5_4

   Sudo (su 'do') allows a system administrator to delegate authority    to give certain users (or groups of users) the ability to run some    (or all) commands as root or another user while providing an audit    trail of the commands and their arguments.

   When a pseudo-command is enabled, sudo permits a match between the    name of the pseudo-command and the name of an executable file in an    arbitrary directory, which allows local users to gain privileges    via a crafted executable file.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0426 to this issue.

   When the runas_default option is used, sudo does not properly set    group memberships, which allows local users to gain privileges via    a sudo command.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0427 to this issue.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-3939     Joseph Malicki reported that the dbg_lvl sysfs attribute     for the megaraid_sas device driver had world-writable     permissions, permitting local users to modify logging     settings.

  - CVE-2009-4027     Lennert Buytenhek reported a race in the mac80211     subsystem that may allow remote users to cause a denial     of service (system crash) on a system connected to the     same wireless network.

  - CVE-2009-4536 CVE-2009-4538     Fabian Yamaguchi reported issues in the e1000 and e1000e     drivers for Intel gigabit network adapters which allow     remote users to bypass packet filters using specially     crafted ethernet frames.

  - CVE-2010-0003     Andi Kleen reported a defect which allows local users to     gain read access to memory reachable by the kernel when     the print-fatal-signals option is enabled. This option     is disabled by default.

  - CVE-2010-0007     Florian Westphal reported a lack of capability checking     in the ebtables netfilter subsystem. If the ebtables     module is loaded, local users can add and modify     ebtables rules.

  - CVE-2010-0291     Al Viro reported several issues with the mmap/mremap     system calls that allow local users to cause a denial of     service (system panic) or obtain elevated privileges.

  - CVE-2010-0298 & CVE-2010-0306     Gleb Natapov discovered issues in the KVM subsystem     where missing permission checks (CPL/IOPL) permit a user     in a guest system to denial of service a guest (system     crash) or gain escalated privileges with the guest.

  - CVE-2010-0307     Mathias Krause reported an issue with the     load_elf_binary code on the amd64 flavor kernels that     allows local users to cause a denial of service (system     crash).

  - CVE-2010-0309     Marcelo Tosatti fixed an issue in the PIT emulation code     in the KVM subsystem that allows privileged users in a     guest domain to cause a denial of service (crash) of the     host system.

  - CVE-2010-0410     Sebastian Krahmer discovered an issue in the netlink     connector subsystem that permits local users to allocate     large amounts of system memory resulting in a denial of     service (out of memory).

  - CVE-2010-0415     Ramon de Carvalho Valle discovered an issue in the     sys_move_pages interface, limited to amd64, ia64 and     powerpc64 flavors in Debian. Local users can exploit     this issue to cause a denial of service (system crash)     or gain access to sensitive kernel memory.

The SUSE Linux Enterprise 11 Kernel was updated to 2.6.27.45 fixing various bugs and security issues.

  - The wake_futex_pi function in kernel/futex.c in the     Linux kernel before 2.6.33-rc7 does not properly handle     certain unlock operations for a Priority Inheritance     (PI) futex, which allows local users to cause a denial     of service (OOPS) and possibly have unspecified other     impact via vectors involving modification of the futex     value from user space. (CVE-2010-0622)

  - The load_elf_binary function in fs/binfmt_elf.c in the     Linux kernel before 2.6.32.8 on the x86_64 platform does     not ensure that the ELF interpreter is available before     a call to the SET_PERSONALITY macro, which allows local     users to cause a denial of service (system crash) via a     32-bit application that attempts to execute a 64-bit     application and then triggers a segmentation fault, as     demonstrated by amd64_killer, related to the     flush_old_exec function. (CVE-2010-0307)

  - Users could send/allocate arbitrary amounts of     NETLINK_CONNECTOR messages to the kernel, causing OOM     condition, killing selected processes or halting the     system. (CVE-2010-0410)

  - The do_pages_move function in mm/migrate.c in the Linux     kernel before 2.6.33-rc7 does not validate node values,     which allows local users to read arbitrary kernel memory     locations, cause a denial of service (OOPS), and     possibly have unspecified other impact by specifying a     node that is not part of the kernels node set.
    (CVE-2010-0415)

  - net/bridge/netfilter/ebtables.c in the ebtables module     in the netfilter framework in the Linux kernel before     2.6.33-rc4 does not require the CAP_NET_ADMIN capability     for setting or modifying rules, which allows local users     to bypass intended access restrictions and configure     arbitrary network-traffic filtering via a modified     ebtables application. (CVE-2010-0007)

  - drivers/net/e1000/e1000_main.c in the e1000 driver in     the Linux kernel 2.6.32.3 and earlier handles Ethernet     frames that exceed the MTU by processing certain     trailing payload data as if it were a complete frame,     which allows remote attackers to bypass packet filters     via a large packet with a crafted payload.
    (CVE-2009-4536)

  - drivers/net/e1000e/netdev.c in the e1000e driver in the     Linux kernel 2.6.32.3 and earlier does not properly     check the size of an Ethernet frame that exceeds the     MTU, which allows remote attackers to have an     unspecified impact via crafted packets. (CVE-2009-4538)

  - The print_fatal_signal function in kernel/signal.c in     the Linux kernel before 2.6.32.4 on the i386 platform,     when print-fatal-signals is enabled, allows local users     to discover the contents of arbitrary memory locations     by jumping to an address and then reading a log file,     and might allow local users to cause a denial of service     (system slowdown or crash) by jumping to an address.
    (CVE-2010-0003)

  - The poll_mode_io file for the megaraid_sas driver in the     Linux kernel 2.6.31.6 and earlier has world-writable     permissions, which allows local users to change the I/O     mode of the driver by modifying this file.
    (CVE-2009-3939)

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2010-141:01 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system.  The     kernel handles the basic functions of the operating system:  memory allocation, process allocation, device     input and output, etc.
    Security bugs fixed with this release:
    CVE-2009-3612     The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x     before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member,     which might allow local users to obtain sensitive information from kernel memory via unspecified vectors.
    NOTE: this issue exists because of an incomplete fix for CVE-2005-4881.
    CVE-2009-3620     The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify     Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of     service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl     calls.
    CVE-2009-3621     net/unix/af_unix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of     service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown     operation on this socket, and then performing a series of connect operations to this socket.
    CVE-2009-3726     The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4     allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a     certain response containing incorrect file attributes, which trigger attempted use of an open file that     lacks NFSv4 state.
    CVE-2007-4567     Linux kernel 2.6.22 and earlier, and possibly other versions, does not properly validate the hop-by-hop     IPv6 extended header, which allows remote attackers to cause a denial of service (kernel panic) via a     crafted IPv6 packet.
    CVE-2009-4536     drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel 2.6.32.3 and earlier handles     Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete     frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload.
    NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1385.
    CVE-2009-4537     drivers/net/r8169.c in the r8169 driver in the Linux kernel 2.6.32.3 and earlier does not properly check     the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to (1) cause a denial of     service (temporary network outage) via a packet with a crafted size, in conjunction with certain packets     containing A characters and certain packets containing E characters; or (2) cause a denial of service     (system crash) via a packet with a crafted size, in conjunction with certain packets containing '0'     characters, related to the value of the status register and erroneous behavior associated with the     RxMaxSize register. NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1389.
    CVE-2009-4538     drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel 2.6.32.3 and earlier does not     properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have     an unspecified impact via crafted packets, a related issue to CVE-2009-4537.
    CVE-2009-4036     No description available at the time of writing.
    CVE-2009-2910     arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x86_64 platform does not clear     certain kernel registers before a return to user mode, which allows local users to read register values     from an earlier process by switching an ia32 process to 64-bit mode.
    CVE-2009-3080     Array index error in the gdth_read_event function in drivers/scsi/gdth.c in the Linux kernel before     2.6.32-rc8 allows local users to cause a denial of service or possibly gain privileges via a negative     event index in an IOCTL request.
    CVE-2009-3556     A certain Red Hat configuration step for the qla2xxx driver in the Linux kernel 2.6.18 on Red Hat     Enterprise Linux (RHEL) 5, when N_Port ID Virtualization (NPIV) hardware is used, sets world-writable     permissions for the (1) vport_create and (2) vport_delete files under /sys/class/scsi_host/, which allows     local users to make arbitrary changes to SCSI host attributes by modifying these files.
    CVE-2009-3889     The dbg_lvl file for the megaraid_sas driver in the Linux kernel before 2.6.27 has world-writable     permissions, which allows local users to change the (1) behavior and (2) logging level of the driver by     modifying this file.
    CVE-2009-3939     The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-     writable permissions, which allows local users to change the I/O mode of the driver by modifying this     file.

Problem description

The SUSE Linux Enterprise 11 Kernel was updated to 2.6.27.42 fixing various bugs and security issues.

The following security issues were fixed :

  - A underflow in the e1000 jumbo ethernet frame handling     could be use by link-local remote attackers to crash the     machine or potentially execute code in kernel context.
    This requires the attacker to be able to send Jumbo     Frames to the target machine. (CVE-2009-4536)

  - A underflow in the e1000e jumbo ethernet frame handling     could be use by link-local remote attackers to crash the     machine or potentially execute code in kernel context.
    This requires the attacker to be able to send Jumbo     Frames to the target machine. (CVE-2009-4538)

  - drivers/firewire/ohci.c in the Linux kernel, when     packet-per-buffer mode is used, allows local users to     cause a denial of service (NULL pointer dereference and     system crash) or possibly have unknown other impact via     an unspecified ioctl associated with receiving an ISO     packet that contains zero in the payload-length field.
    (CVE-2009-4138)

  - The ext4_fill_flex_info function in fs/ext4/super.c in     the Linux kernel allows user-assisted remote attackers     to cause a denial of service (divide-by-zero error and     panic) via a malformed ext4 filesystem containing a     super block with a large FLEX_BG group size (aka     s_log_groups_per_flex value). (CVE-2009-4307)

  - The ext4_decode_error function in fs/ext4/super.c in the     ext4 filesystem in the Linux kernel before 2.6.32 allows     user-assisted remote attackers to cause a denial of     service (NULL pointer dereference), and possibly have     unspecified other impact, via a crafted read-only     filesystem that lacks a journal. (CVE-2009-4308)

  - The poll_mode_io file for the megaraid_sas driver in the     Linux kernel has world-writable permissions, which     allows local users to change the I/O mode of the driver     by modifying this file. (CVE-2009-3939)

  - The collect_rx_frame function in     drivers/isdn/hisax/hfc_usb.c in the Linux kernel allows     attackers to have an unspecified impact via a crafted     HDLC packet that arrives over ISDN and triggers a buffer     under-read. (CVE-2009-4005)

  - A negative offset in a ioctl in the GDTH RAID driver was     fixed. (CVE-2009-3080)

  - Stack-based buffer overflow in the hfs subsystem in the     Linux kernel allows remote attackers to have an     unspecified impact via a crafted Hierarchical File     System (HFS) filesystem, related to the hfs_readdir     function in fs/hfs/dir.c. (CVE-2009-4020)
