The openSUSE 11.0 kernel was updated to 2.6.25.16.

It fixes various stability bugs and also security bugs.

CVE-2008-1673: Fixed the range checking in the ASN.1 decoder in NAT for SNMP and CIFS, which could have been used by a remote attacker to crash the machine.

CVE-2008-3276: An integer overflow flaw was found in the Linux kernel dccp_setsockopt_change() function. An attacker may leverage this vulnerability to trigger a kernel panic on a victim's machine remotely.

CVE-2008-3272: The snd_seq_oss_synth_make_info function in sound/core/seq/oss/seq_oss_synth.c in the sound subsystem does not verify that the device number is within the range defined by max_synthdev before returning certain data to the caller, which allows local users to obtain sensitive information.

CVE-2008-3275: The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ('overflow' of the UBIFS orphan area) via a series of attempted file creations within deleted directories.

Also lots of bugs were fixed.

Updated kernel packages that resolve several security issues and fix various bugs are now available for Red Hat Enterprise Linux 3.

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 addresses the following security issues :

* Tavis Ormandy discovered a deficiency in the Linux kernel 32-bit and 64-bit emulation. This could allow a local, unprivileged user to prepare and run a specially crafted binary which would use this deficiency to leak uninitialized and potentially sensitive data.
(CVE-2008-0598, Important)

* a possible kernel memory leak was found in the Linux kernel Simple Internet Transition (SIT) INET6 implementation. This could allow a local, unprivileged user to cause a denial of service. (CVE-2008-2136, Important)

* missing capability checks were found in the SBNI WAN driver which could allow a local user to bypass intended capability restrictions.
(CVE-2008-3525, Important)

* the do_truncate() and generic_file_splice_write() functions did not clear the setuid and setgid bits. This could allow a local, unprivileged user to obtain access to privileged information.
(CVE-2008-4210, Important)

* a buffer overflow flaw was found in Integrated Services Digital Network (ISDN) subsystem. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2007-6063, Moderate)

* multiple NULL pointer dereferences were found in various Linux kernel network drivers. These drivers were missing checks for terminal validity, which could allow privilege escalation. (CVE-2008-2812, Moderate)

* a deficiency was found in the Linux kernel virtual filesystem (VFS) implementation. This could allow a local, unprivileged user to attempt file creation within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)

This update also fixes the following bugs :

* the incorrect kunmap function was used in nfs_xdr_readlinkres.
kunmap() was used where kunmap_atomic() should have been. As a consequence, if an NFSv2 or NFSv3 server exported a volume containing a symlink which included a path equal to or longer than the local system's PATH_MAX, accessing the link caused a kernel oops. This has been corrected in this update.

* mptctl_gettargetinfo did not check if pIoc3 was NULL before using it as a pointer. This caused a kernel panic in mptctl_gettargetinfo in some circumstances. A check has been added which prevents this.

* lost tick compensation code in the timer interrupt routine triggered without apparent cause. When running as a fully-virtualized client, this spurious triggering caused the 64-bit version of Red Hat Enterprise Linux 3 to present highly inaccurate times. With this update the lost tick compensation code is turned off when the operating system is running as a fully-virtualized client under Xen or VMware(r).

All Red Hat Enterprise Linux 3 users should install this updated kernel which addresses these vulnerabilities and fixes these bugs.

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in the following components :

  - ISC DHCP dhclient
  - Integrated Services Digital Network (ISDN) subsystem
  - Java Runtime Environment (JRE)
  - Java SE Development Kit (JDK)
  - Java SE Web Start
  - Linux kernel
  - Linux kernel 32-bit and 64-bit emulation
  - Linux kernel Simple Internet Transition INET6
  - Linux kernel tty
  - Linux kernel virtual file system (VFS)
  - Red Hat dhcpd init script for DHCP
  - SBNI WAN driver

It was discovered that there were multiple NULL pointer function dereferences in the Linux kernel terminal handling code. A local attacker could exploit this to execute arbitrary code as root, or crash the system, leading to a denial of service. (CVE-2008-2812)

The do_change_type routine did not correctly validation administrative users. A local attacker could exploit this to block mount points or cause private mounts to be shared, leading to denial of service or a possible loss of privacy. (CVE-2008-2931)

Tobias Klein discovered that the OSS interface through ALSA did not correctly validate the device number. A local attacker could exploit this to access sensitive kernel memory, leading to a denial of service or a loss of privacy. (CVE-2008-3272)

Zoltan Sogor discovered that new directory entries could be added to already deleted directories. A local attacker could exploit this, filling up available memory and disk space, leading to a denial of service. (CVE-2008-3275)

In certain situations, the fix for CVE-2008-0598 from USN-623-1 was causing infinite loops in the writev syscall. This update corrects the mistake. We apologize for the inconvenience.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated kernel packages that fix various security issues and several bugs are now available for Red Hat Enterprise Linux 5.

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.

Security fixes :

* a missing capability check was found in the Linux kernel do_change_type routine. This could allow a local unprivileged user to gain privileged access or cause a denial of service. (CVE-2008-2931, Important)

* a flaw was found in the Linux kernel Direct-IO implementation. This could allow a local unprivileged user to cause a denial of service.
(CVE-2007-6716, Important)

* Tobias Klein reported a missing check in the Linux kernel Open Sound System (OSS) implementation. This deficiency could lead to a possible information leak. (CVE-2008-3272, Moderate)

* a deficiency was found in the Linux kernel virtual filesystem (VFS) implementation. This could allow a local unprivileged user to attempt file creation within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)

* a flaw was found in the Linux kernel tmpfs implementation. This could allow a local unprivileged user to read sensitive information from the kernel. (CVE-2007-6417, Moderate)

Bug fixes :

* when copying a small IPoIB packet from the original skb it was received in to a new, smaller skb, all fields in the new skb were not initialized. This may have caused a kernel oops.

* previously, data may have been written beyond the end of an array, causing memory corruption on certain systems, resulting in hypervisor crashes during context switching.

* a kernel crash may have occurred on heavily-used Samba servers after 24 to 48 hours of use.

* under heavy memory pressure, pages may have been swapped out from under the SGI Altix XPMEM driver, causing silent data corruption in the kernel.

* the ixgbe driver is untested, but support was advertised for the Intel 82598 network card. If this card was present when the ixgbe driver was loaded, a NULL pointer dereference and a panic occurred.

* on certain systems, if multiple InfiniBand queue pairs simultaneously fell into an error state, an overrun may have occurred, stopping traffic.

* with bridging, when forward delay was set to zero, setting an interface to the forwarding state was delayed by one or possibly two timers, depending on whether STP was enabled. This may have caused long delays in moving an interface to the forwarding state. This issue caused packet loss when migrating virtual machines, preventing them from being migrated without interrupting applications.

* on certain multinode systems, IPMI device nodes were created in reverse order of where they physically resided.

* process hangs may have occurred while accessing application data files via asynchronous direct I/O system calls.

* on systems with heavy lock traffic, a possible deadlock may have caused anything requiring locks over NFS to stop, or be very slow.
Errors such as 'lockd: server [IP] not responding, timed out' were logged on client systems.

* unexpected removals of USB devices may have caused a NULL pointer dereference in kobject_get_path.

* on Itanium-based systems, repeatedly creating and destroying Windows guests may have caused Dom0 to crash, due to the 'XENMEM_add_to_physmap' hypercall, used by para-virtualized drivers on HVM, being SMP-unsafe.

* when using an MD software RAID, crashes may have occurred when devices were removed or changed while being iterated through. Correct locking is now used.

* break requests had no effect when using 'Serial Over Lan' with the Intel 82571 network card. This issue may have caused log in problems.

* on Itanium-based systems, module_free() referred the first parameter before checking it was valid. This may have caused a kernel panic when exiting SystemTap.

Red Hat Enterprise Linux 5 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

From Red Hat Security Advisory 2009:0014 :

Updated kernel packages that resolve several security issues and fix various 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 addresses the following security issues :

* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)

* when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a local denial of service.
(CVE-2008-5029, Important)

* a deficiency was found in the Linux kernel virtual file system (VFS) implementation. This could allow a local, unprivileged user to make a series of file creations within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)

* a buffer underflow flaw was found in the Linux kernel IB700 SBC watchdog timer driver. This deficiency could lead to a possible information leak. By default, the '/dev/watchdog' device is accessible only to the root user. (CVE-2008-5702, Low)

* the hfs and hfsplus file systems code failed to properly handle corrupted data structures. This could, potentially, lead to a local denial of service. (CVE-2008-4933, CVE-2008-5025, Low)

* a flaw was found in the hfsplus file system implementation. This could, potentially, lead to a local denial of service when write operations were performed. (CVE-2008-4934, Low)

This update also fixes the following bugs :

* when running Red Hat Enterprise Linux 4.6 and 4.7 on some systems running Intel(r) CPUs, the cpuspeed daemon did not run, preventing the CPU speed from being changed, such as not being reduced to an idle state when not in use.

* mmap() could be used to gain access to beyond the first megabyte of RAM, due to insufficient checks in the Linux kernel code. Checks have been added to prevent this.

* attempting to turn keyboard LEDs on and off rapidly on keyboards with slow keyboard controllers, may have caused key presses to fail.

* after migrating a hypervisor guest, the MAC address table was not updated, causing packet loss and preventing network connections to the guest. Now, a gratuitous ARP request is sent after migration. This refreshes the ARP caches, minimizing network downtime.

* writing crash dumps with diskdump may have caused a kernel panic on Non-Uniform Memory Access (NUMA) systems with certain memory configurations.

* on big-endian systems, such as PowerPC, the getsockopt() function incorrectly returned 0 depending on the parameters passed to it when the time to live (TTL) value equaled 255, possibly causing memory corruption and application crashes.

* a problem in the kernel packages provided by the RHSA-2008:0508 advisory caused the Linux kernel's built-in memory copy procedure to return the wrong error code after recovering from a page fault on AMD64 and Intel 64 systems. This may have caused other Linux kernel functions to return wrong error codes.

* a divide-by-zero bug in the Linux kernel process scheduler, which may have caused kernel panics on certain systems, has been resolved.

* the netconsole kernel module caused the Linux kernel to hang when slave interfaces of bonded network interfaces were started, resulting in a system hang or kernel panic when restarting the network.

* the '/proc/xen/' directory existed even if systems were not running Red Hat Virtualization. This may have caused problems for third-party software that checks virtualization-ability based on the existence of '/proc/xen/'. Note: this update will remove the '/proc/xen/' directory on systems not running Red Hat Virtualization.

All Red Hat Enterprise Linux 4 users should upgrade to these updated packages, which contain backported patches to resolve these issues.

a. Service Console update for DHCP and third-party library update    for DHCP client.

   DHCP is an Internet-standard protocol by which a computer can be    connected to a local network, ask to be given configuration    information, and receive from a server enough information to    configure itself as a member of that network.

   A stack-based buffer overflow in the script_write_params method in    ISC DHCP dhclient allows remote DHCP servers to execute arbitrary    code via a crafted subnet-mask option.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-0692 to this issue.

   An insecure temporary file use flaw was discovered in the DHCP    daemon's init script ('/etc/init.d/dhcpd'). A local attacker could    use this flaw to overwrite an arbitrary file with the output of the    'dhcpd -t' command via a symbolic link attack, if a system    administrator executed the DHCP init script with the 'configtest',    'restart', or 'reload' option.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-1893 to this issue.

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2008-519:09 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.
    Bugs fixed:
    CVE-2007-6417:
    The shmem_getpage function (mm/shmem.c) in Linux kernel 2.6.11 through 2.6.23 does not properly clear     allocated memory in some rare circumstances related to tmpfs, which might allow local users to read     sensitive kernel data or cause a denial of service (crash).
    CVE-2007-6716:
    fs/direct-io.c in the dio subsystem in the Linux kernel before 2.6.23 does not properly zero out the dio     struct, which allows local users to cause a denial of service (OOPS), as demonstrated by a certain fio     test.
    CVE-2008-2931:
    The do_change_type function in fs/namespace.c in the Linux kernel before 2.6.22 does not verify that the     caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of     service by modifying the properties of a mountpoint.
    CVE-2008-3272:
    The snd_seq_oss_synth_make_info function in sound/core/seq/oss/seq_oss_synth.c in the sound subsystem in     the Linux kernel before 2.6.27-rc2 does not verify that the device number is within the range defined by     max_synthdev before returning certain data to the caller, which allows local users to obtain sensitive     information.
    CVE-2008-3275:
    The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation in the Linux     kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory,     which allows local users to cause a denial of service (overflow of the UBIFS orphan area) via a series of     attempted file creations within deleted directories.
    - fixes a bug in which the ipmi_si driverdid not load successfully and crash-dumping could not complete.
    - adds support for ARC-1200 disks.
    - when configuring bonding device (2 slave devices connected to a repeater hub) as active-backup, ipv6 DAD     fails with the following message on the console:
    bond0:duplicate address detected!
    - repetition of kdumping via /proc/sysrq-trigger would trigger a lockup detected by NMI watchdog.

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.

This update of the SUSE Linux Enterprise 10 Service Pack 1 kernel contains lots of bugfixes and several security fixes :

  - Added missing capability checks in sbni_ioctl().
    (CVE-2008-3525)

  - On AMD64 some string operations could leak kernel     information into userspace. (CVE-2008-0598)

  - Added range checking in ASN.1 handling for the CIFS and     SNMP NAT netfilter modules. (CVE-2008-1673)

  - Fixed range checking in the snd_seq OSS ioctl, which     could be used to leak information from the kernel.
    (CVE-2008-3272)

  - Fixed a memory leak when looking up deleted directories     which could be used to run the system out of memory.
    (CVE-2008-3275)

  - The do_change_type function in fs/namespace.c did not     verify that the caller has the CAP_SYS_ADMIN capability,     which allows local users to gain privileges or cause a     denial of service by modifying the properties of a     mountpoint. (CVE-2008-2931)

  - Various NULL ptr checks have been added to tty op     functions, which might have been used by local attackers     to execute code. We think that this affects only devices     openable by root, so the impact is limited.
    (CVE-2008-2812)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or arbitrary code execution. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-6282     Dirk Nehring discovered a vulnerability in the IPsec     code that allows remote users to cause a denial of     service by sending a specially crafted ESP packet.

  - CVE-2008-0598     Tavis Ormandy discovered a vulnerability that allows     local users to access uninitialized kernel memory,     possibly leaking sensitive data. This issue is specific     to the amd64-flavour kernel images.

  - CVE-2008-2729     Andi Kleen discovered an issue where uninitialized     kernel memory was being leaked to userspace during an     exception. This issue may allow local users to gain     access to sensitive data. Only the amd64-flavour Debian     kernel images are affected.

  - CVE-2008-2812     Alan Cox discovered an issue in multiple tty drivers     that allows local users to trigger a denial of service     (NULL pointer dereference) and possibly obtain elevated     privileges.

  - CVE-2008-2826     Gabriel Campana discovered an integer overflow in the     sctp code that can be exploited by local users to cause     a denial of service.

  - CVE-2008-2931     Miklos Szeredi reported a missing privilege check in the     do_change_type() function. This allows local,     unprivileged users to change the properties of mount     points.

  - CVE-2008-3272     Tobias Klein reported a locally exploitable data leak in     the snd_seq_oss_synth_make_info() function. This may     allow local users to gain access to sensitive     information.

  - CVE-2008-3275     Zoltan Sogor discovered a coding error in the VFS that     allows local users to exploit a kernel memory leak     resulting in a denial of service.

This update addresses the following security issues :

  - the sendmsg() function in the Linux kernel did not block     during UNIX socket garbage collection. This could,     potentially, lead to a local denial of service.
    (CVE-2008-5300, Important)

  - when fput() was called to close a socket, the
    __scm_destroy() function in the Linux kernel could make     indirect recursive calls to itself. This could,     potentially, lead to a local denial of service.
    (CVE-2008-5029, Important)

  - a deficiency was found in the Linux kernel virtual file     system (VFS) implementation. This could allow a local,     unprivileged user to make a series of file creations     within deleted directories, possibly causing a denial of     service. (CVE-2008-3275, Moderate)

  - a buffer underflow flaw was found in the Linux kernel     IB700 SBC watchdog timer driver. This deficiency could     lead to a possible information leak. By default, the     '/dev/watchdog' device is accessible only to the root     user. (CVE-2008-5702, Low)

  - the hfs and hfsplus file systems code failed to properly     handle corrupted data structures. This could,     potentially, lead to a local denial of service.
    (CVE-2008-4933, CVE-2008-5025, Low)

  - a flaw was found in the hfsplus file system     implementation. This could, potentially, lead to a local     denial of service when write operations were performed.
    (CVE-2008-4934, Low)

This update also fixes the following bugs :

  - when running Red Hat Enterprise Linux 4.6 and 4.7 on     some systems running Intel&reg; CPUs, the cpuspeed     daemon did not run, preventing the CPU speed from being     changed, such as not being reduced to an idle state when     not in use.

  - mmap() could be used to gain access to beyond the first     megabyte of RAM, due to insufficient checks in the Linux     kernel code. Checks have been added to prevent this.

  - attempting to turn keyboard LEDs on and off rapidly on     keyboards with slow keyboard controllers, may have     caused key presses to fail.

  - after migrating a hypervisor guest, the MAC address     table was not updated, causing packet loss and     preventing network connections to the guest. Now, a     gratuitous ARP request is sent after migration. This     refreshes the ARP caches, minimizing network downtime.

  - writing crash dumps with diskdump may have caused a     kernel panic on Non-Uniform Memory Access (NUMA) systems     with certain memory configurations.

  - on big-endian systems, such as PowerPC, the getsockopt()     function incorrectly returned 0 depending on the     parameters passed to it when the time to live (TTL)     value equaled 255, possibly causing memory corruption     and application crashes.

  - a problem in the kernel packages provided by the     RHSA-2008:0508 advisory caused the Linux kernel's     built-in memory copy procedure to return the wrong error     code after recovering from a page fault on AMD64 and     Intel 64 systems. This may have caused other Linux     kernel functions to return wrong error codes.

  - a divide-by-zero bug in the Linux kernel process     scheduler, which may have caused kernel panics on     certain systems, has been resolved.

  - the netconsole kernel module caused the Linux kernel to     hang when slave interfaces of bonded network interfaces     were started, resulting in a system hang or kernel panic     when restarting the network.

  - the '/proc/xen/' directory existed even if systems were     not running Red Hat Virtualization. This may have caused     problems for third-party software that checks     virtualization-ability based on the existence of     '/proc/xen/'. Note: this update will remove the     '/proc/xen/' directory on systems not running Red Hat     Virtualization.

This updated kernel-utils package adds an enhancement in the way of proper support for user-space frequency-scaling on multi-core systems.
