    linux vulnerabilities
    A security issue affects these releases of Ubuntu and its derivatives:
    - Ubuntu 10.04 LTS
    Several security issues were fixed in the kernel.
    Software Description:
    - linux: Linux kernel
    Vasily Kulikov discovered a flaw in the Linux Kernel's perf tool that
    allows for privilege escalation. A local user could exploit this flaw to
    run commands as root when using the perf tool.
    Michael S. Tsirkin discovered a flaw in how the Linux kernel's KVM
    subsystem allocates memory slots for the guest's address space. A local
    user could exploit this flaw to gain system privileges or obtain sensitive
    information from kernel memory. (CVE-2013-1943)
    A flaw was discovered in the SCTP (stream control transfer protocol)
    network protocol's handling of duplicate cookies in the Linux kernel. A
    remote attacker could exploit this flaw to cause a denial of service
    (system crash) on another remote user querying the SCTP connection.
    Hannes Frederic Sowa discovered a flaw in setsockopt UDP_CORK option in the
    Linux kernel's IPv6 stack. A local user could exploit this flaw to cause a
    denial of service (system crash). (CVE-2013-4162)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 10.04 LTS:
      linux-image-2.6.32-51-386       2.6.32-51.113
      linux-image-2.6.32-51-generic   2.6.32-51.113
      linux-image-2.6.32-51-generic-pae  2.6.32-51.113
      linux-image-2.6.32-51-ia64      2.6.32-51.113
      linux-image-2.6.32-51-lpia      2.6.32-51.113
      linux-image-2.6.32-51-powerpc   2.6.32-51.113
      linux-image-2.6.32-51-powerpc-smp  2.6.32-51.113
      linux-image-2.6.32-51-powerpc64-smp  2.6.32-51.113
      linux-image-2.6.32-51-preempt   2.6.32-51.113
      linux-image-2.6.32-51-server    2.6.32-51.113
      linux-image-2.6.32-51-sparc64   2.6.32-51.113
      linux-image-2.6.32-51-sparc64-smp  2.6.32-51.113
      linux-image-2.6.32-51-versatile  2.6.32-51.113
      linux-image-2.6.32-51-virtual   2.6.32-51.113
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed. If
    you use linux-restricted-modules, you have to update that package as
    well to get modules which work with the new kernel version. Unless you
    manually uninstalled the standard kernel metapackages (e.g. linux-generic,
    linux-server, linux-powerpc), a standard system upgrade will automatically
    perform this as well.
      CVE-2013-1060, CVE-2013-1943, CVE-2013-2206, CVE-2013-4162
