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.
    CVE-2009-4020     Stack-based buffer overflow in the hfs subsystem in the Linux kernel 2.6.32 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-2009-4021     The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel before 2.6.32-rc7     might allow attackers to cause a denial of service (invalid pointer dereference and OOPS) via vectors     possibly related to a memory-consumption attack.
    CVE-2009-4138     drivers/firewire/ohci.c in the Linux kernel before 2.6.32-git9, 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-2009-4141     Use-after-free vulnerability in the fasync_helper function in fs/fcntl.c in the Linux kernel before     2.6.33-rc4-git1 allows local users to gain privileges via vectors that include enabling O_ASYNC (aka     FASYNC or FIOASYNC) on a locked file, and then closing this file.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

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 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.

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.
