An error was discovered in the Linux kernel's network TUN/TAP device implementation. A local user with access to the TUN/TAP interface (which is not available to unprivileged users until granted by a root user) could exploit this flaw to crash the system or potential gain administrative privileges. (CVE-2012-2136)

Ulrich Obergfell discovered an error in the Linux kernel's memory management subsystem on 32 bit PAE systems with more than 4GB of memory installed. A local unprivileged user could exploit this flaw to crash the system. (CVE-2012-2373)

A flaw was discovered in the Linux kernel's epoll system call. An unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)

Some errors where discovered in the Linux kernel's UDF file system, which is used to mount some CD-ROMs and DVDs. An unprivileged local user could use these flaws to crash the system. (CVE-2012-3400)

The SUSE Linux Enterprise 11 SP2 kernel was updated to 3.0.34, fixing a lot of bugs and security issues.

The update from Linux kernel 3.0.31 to 3.0.34 also fixes various bugs not listed here.

The following security issues have been fixed :

  - Local attackers could trigger an overflow in     sock_alloc_send_pksb(), potentially crashing the machine     or escalate privileges. (CVE-2012-2136)

  - A memory leak in transparent hugepages on mmap failure     could be used by local attacker to run the machine out     of memory (local denial of service). (CVE-2012-2390)

  - A malicious guest driver could overflow the host stack     by passing a long descriptor, so potentially crashing     the host system or escalating privileges on the host.
    (CVE-2012-2119)

  - Malicious NFS server could crash the clients when more     than 2 GETATTR bitmap words are returned in response to     the FATTR4_ACL attribute requests, only incompletely     fixed by CVE-2011-4131. (CVE-2012-2375)

This Linux kernel update fixes various security issues and bugs in the SUSE Linux Enterprise 10 SP4 kernel.

The following security issues have been fixed :

CVE-2011-2494: kernel/taskstats.c in the Linux kernel allowed local users to obtain sensitive I/O statistics by sending taskstats commands to a netlink socket, as demonstrated by discovering the length of another users password (a side channel attack).

CVE-2012-2744: net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux kernel, when the nf_conntrack_ipv6 module is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets.

CVE-2012-3510: Use-after-free vulnerability in the xacct_add_tsk function in kernel/tsacct.c in the Linux kernel allowed local users to obtain potentially sensitive information from kernel memory or cause a denial of service (system crash) via a taskstats TASKSTATS_CMD_ATTR_PID command.

CVE-2011-4110: The user_update function in security/keys/user_defined.c in the Linux kernel 2.6 allowed local users to cause a denial of service (NULL pointer dereference and kernel oops) via vectors related to a user-defined key and updating a negative key into a fully instantiated key.

CVE-2011-1044: The ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel did not initialize a certain response buffer, which allowed local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially filled, a different vulnerability than CVE-2010-4649.

CVE-2012-3400: Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel allowed remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.

CVE-2012-2136: The sock_alloc_send_pskb function in net/core/sock.c in the Linux kernel did not properly validate a certain length value, which allowed local users to cause a denial of service (heap-based buffer overflow and system crash) or possibly gain privileges by leveraging access to a TUN/TAP device.
