"This kernel update for the SUSE Linux Enterprise 10 SP4 kernel fixes
several security issues and bugs.

The following security issues were fixed :

  - The dccp_rcv_state_process function in net/dccp/input.c
    in the Datagram Congestion Control Protocol (DCCP)
    implementation in the Linux kernel did not properly
    handle packets for a CLOSED endpoint, which allowed
    remote attackers to cause a denial of service (NULL
    pointer dereference and OOPS) by sending a DCCP-Close
    packet followed by a DCCP-Reset packet. (CVE-2011-1093)

  - The add_del_listener function in kernel/taskstats.c in
    the Linux kernel did not prevent multiple registrations
    of exit handlers, which allowed local users to cause a
    denial of service (memory and CPU consumption), and
    bypass the OOM Killer, via a crafted application.
    (CVE-2011-2484)

  - Integer overflow in the agp_generic_insert_memory
    function in drivers/char/agp/generic.c in the Linux
    kernel allowed local users to gain privileges or cause a
    denial of service (system crash) via a crafted
    AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745)

  - Multiple integer overflows in the (1)
    agp_allocate_memory and (2) agp_create_user_memory
    functions in drivers/char/agp/generic.c in the Linux
    kernel allowed local users to trigger buffer overflows,
    and consequently cause a denial of service (system
    crash) or possibly have unspecified other impact, via
    vectors related to calls that specify a large number of
    memory pages. (CVE-2011-1746)

  - The agp_generic_remove_memory function in
    drivers/char/agp/generic.c in the Linux kernel before
    2.6.38.5 did not validate a certain start parameter,
    which allowed local users to gain privileges or cause a
    denial of service (system crash) via a crafted
    AGPIOC_UNBIND agp_ioctl ioctl call, a different
    vulnerability than CVE-2011-1745. (CVE-2011-2022)

  - When using a setuid root mount.cifs, local users could
    hijack password protected mounted CIFS shares of other
    local users. (CVE-2011-1585)

  - The do_task_stat function in fs/proc/array.c in the
    Linux kernel did not perform an expected uid check,
    which made it easier for local users to defeat the ASLR
    protection mechanism by reading the start_code and
    end_code fields in the /proc/#####/stat file for a
    process executing a PIE binary. (CVE-2011-0726)

  - The normal mmap paths all avoid creating a mapping where
    the pgoff inside the mapping could wrap around due to
    overflow. However, an expanding mremap() can take such a
    non-wrapping mapping and make it bigger and cause a
    wrapping condition. (CVE-2011-2496)

  - A local unprivileged user able to access a NFS
    filesystem could use file locking to deadlock parts of
    an nfs server under some circumstance. (CVE-2011-2491)

  - The code for evaluating LDM partitions (in
    fs/partitions/ldm.c) contained bugs that could crash the
    kernel for certain corrupted LDM partitions.
    (CVE-2011-1017 / CVE-2011-2182)

  - Multiple integer overflows in the next_pidmap function
    in kernel/pid.c in the Linux kernel allowed local users
    to cause a denial of service (system crash) via a
    crafted (1) getdents or (2) readdir system call.
    (CVE-2011-1593)

  - Integer overflow in the _ctl_do_mpt_command function in
    drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel
    might have allowed local users to gain privileges or
    cause a denial of service (memory corruption) via an
    ioctl call specifying a crafted value that triggers a
    heap-based buffer overflow. (CVE-2011-1494)

  - drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel
    did not validate (1) length and (2) offset values before
    performing memory copy operations, which might have
    allowed local users to gain privileges, cause a denial
    of service (memory corruption), or obtain sensitive
    information from kernel memory via a crafted ioctl call,
    related to the _ctl_do_mpt_command and
    _ctl_diag_read_buffer functions. (CVE-2011-1495)"
