    Ubuntu Security Notice USN-1678-1
    December 20, 2012
    
    linux-lts-backport-oneiric vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 10.04 LTS
    
    Summary:
    
    The system could be made to crash under certain conditions.
    
    Software Description:
    - linux-lts-backport-oneiric: Linux kernel backport from Oneiric
    
    Details:
    
    A flaw was discovered in the Linux kernel's handling of new hot-plugged
    memory. An unprivileged local user could exploit this flaw to cause a
    denial of service by crashing the system.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 10.04 LTS:
      linux-image-3.0.0-29-generic    3.0.0-29.46~lucid1
      linux-image-3.0.0-29-generic-pae  3.0.0-29.46~lucid1
      linux-image-3.0.0-29-server     3.0.0-29.46~lucid1
      linux-image-3.0.0-29-virtual    3.0.0-29.46~lucid1
    
    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.
