The SUSE Linux Enterprise 11 SP1 kernel was updated to 2.6.32.54, fixing lots of bugs and security issues.

The following security issues have been fixed :

  - A potential hypervisor escape by issuing SG_IO commands     to partitiondevices was fixed by restricting access to     these commands. (CVE-2011-4127)

  - KEYS: Fix a NULL pointer deref in the user-defined key     type, which allowed local attackers to Oops the kernel.
    (CVE-2011-4110)

  - Avoid potential NULL pointer deref in ghash, which     allowed local attackers to Oops the kernel.
    (CVE-2011-4081)

  - Fixed a memory corruption possibility in xfs readlink,     which could be used by local attackers to crash the     system or potentially execute code by mounting a     prepared xfs filesystem image. (CVE-2011-4077)

  - A overflow in the xfs acl handling was fixed that could     be used by local attackers to crash the system or     potentially execute code by mounting a prepared xfs     filesystem image. (CVE-2012-0038)

  - A flaw in the ext3/ext4 filesystem allowed a local     attacker to crash the kernel by getting a prepared     ext3/ext4 filesystem mounted. (CVE-2011-4132)

  - Access to the taskstats /proc file was restricted to     avoid local attackers gaining knowledge of IO of other     users (and so effecting side-channel attacks for e.g.
    guessing passwords by typing speed). (CVE-2011-2494)

  - When using X.25 communication a malicious sender could     corrupt data structures, causing crashes or potential     code execution. Please note that X.25 needs to be setup     to make this effective, which these days is usually not     the case. (CVE-2010-3873)

  - When using X.25 communication a malicious sender could     make the machine leak memory, causing crashes. Please     note that X.25 needs to be setup to make this effective,     which these days is usually not the case.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0010 advisory.

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

    This update fixes the following security issues:

    * A malicious CIFS (Common Internet File System) server could send a     specially-crafted response to a directory read request that would result in     a denial of service or privilege escalation on a system that has a CIFS     share mounted. (CVE-2011-3191, Important)

    * The way fragmented IPv6 UDP datagrams over the bridge with UDP     Fragmentation Offload (UFO) functionality on were handled could allow a     remote attacker to cause a denial of service. (CVE-2011-4326, Important)

    * GRO (Generic Receive Offload) fields could be left in an inconsistent     state. An attacker on the local network could use this flaw to cause a     denial of service. GRO is enabled by default in all network drivers that     support it. (CVE-2011-2723, Moderate)

    * IPv4 and IPv6 protocol sequence number and fragment ID generation could     allow a man-in-the-middle attacker to inject packets and possibly hijack     connections. Protocol sequence numbers and fragment IDs are now more     random. (CVE-2011-3188, Moderate)

    * A flaw in the FUSE (Filesystem in Userspace) implementation could allow     a local user in the fuse group who has access to mount a FUSE file system     to cause a denial of service. (CVE-2011-3353, Moderate)

    * A flaw in the b43 driver. If a system had an active wireless interface     that uses the b43 driver, an attacker able to send a specially-crafted     frame to that interface could cause a denial of service. (CVE-2011-3359,     Moderate)

    * A flaw in the way CIFS shares with DFS referrals at their root were     handled could allow an attacker on the local network, who is able to deploy     a malicious CIFS server, to create a CIFS network share that, when mounted,     would cause the client system to crash. (CVE-2011-3363, Moderate)

    * A flaw in the m_stop() implementation could allow a local, unprivileged     user to trigger a denial of service. (CVE-2011-3637, Moderate)

    * Flaws in ghash_update() and ghash_final() could allow a local,     unprivileged user to cause a denial of service. (CVE-2011-4081, Moderate)

    * A flaw in the key management facility could allow a local, unprivileged     user to cause a denial of service via the keyctl utility. (CVE-2011-4110,     Moderate)

    * A flaw in the Journaling Block Device (JBD) could allow a local attacker     to crash the system by mounting a specially-crafted ext3 or ext4 disk.
    (CVE-2011-4132, Moderate)

    * A flaw in the way memory containing security-related data was handled in     tpm_read() could allow a local, unprivileged user to read the results of a     previously run TPM command. (CVE-2011-1162, Low)

    * I/O statistics from the taskstats subsystem could be read without any     restrictions, which could allow a local, unprivileged user to gather     confidential information, such as the length of a password used in a     process. (CVE-2011-2494, Low)

    * Flaws in tpacket_rcv() and packet_recvmsg() could allow a local,     unprivileged user to leak information to user-space. (CVE-2011-2898, Low)

    Red Hat would like to thank Darren Lavender for reporting CVE-2011-3191;
    Brent Meshier for reporting CVE-2011-2723; Dan Kaminsky for reporting     CVE-2011-3188; Yogesh Sharma for reporting CVE-2011-3363; Nick Bowler for     reporting CVE-2011-4081; Peter Huewe for reporting CVE-2011-1162; and     Vasiliy Kulikov of Openwall for reporting CVE-2011-2494.

    This update also fixes the following bugs:

    * Previously, a mismatch in the build-id of the kernel-rt and the one in     the related debuginfo package caused failures in SystemTap and perf.
    (BZ#768413)

    * IBM x3650m3 systems were not able to boot the MRG Realtime kernel because     they require a pmcraid driver that was not available. The pmcraid driver is     included in this update. (BZ#753992)

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