    Ubuntu Security Notice USN-1849-1
    May 31, 2013
    
    linux-lts-raring vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    
    Summary:
    
    The system could be made to crash or run programs as an administrator if
    it received specially crafted network traffic.
    
    Software Description:
    - linux-lts-raring: Linux hardware enablement kernel from Raring
    
    Details:
    
    Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote
    unauthenticated attacker could exploit this flaw to cause a denial of
    service (system crash) or potentially gain administrative privileges.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      linux-image-3.8.0-23-generic    3.8.0-23.34~precise1
    
    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.
