    linux-ec2 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-ec2: Linux kernel for EC2
    Stephan Mueller reported an error in the Linux kernel's ansi cprng random
    number generator. This flaw makes it easier for a local attacker to break
    cryptographic protections. (CVE-2013-4345)
    A flaw was discovered in the Linux kernel's IP Virtual Server (IP_VS)
    support. A local user with the CAP_NET_ADMIN capability could exploit this
    flaw to gain additional administrative privileges. (CVE-2013-4588)
    Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's
    debugfs filesystem. An administrative local user could exploit this flaw to
    cause a denial of service (OOPS). (CVE-2013-6378)
    Nico Golde reported a flaw in the Linux kernel's userspace IO (uio) driver.
    A local user could exploit this flaw to cause a denial of service (memory
    corruption) or possibly gain privileges. (CVE-2013-6763)
    Update instructions:
    The problem can be corrected by updating your system to the following
    package versions:
    Ubuntu 10.04 LTS:
      linux-image-2.6.32-360-ec2      2.6.32-360.73
    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-2013-4345, CVE-2013-4588, CVE-2013-6378, CVE-2013-6763
