    Ubuntu Security Notice USN-2744-1
    September 24, 2015
    
    apport vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.04
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Apport could be made to crash or overwrite files as an administrator.
    
    Software Description:
    - apport: automatically generate crash reports for debugging
    
    Details:
    
    Halfdog discovered that Apport incorrectly handled kernel crash dump files.
    A local attacker could use this issue to cause a denial of service, or
    possibly elevate privileges. The default symlink protections for affected
    releases should reduce the vulnerability to a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.04:
      apport                          2.17.2-0ubuntu1.5
    
    Ubuntu 14.04 LTS:
      apport                          2.14.1-0ubuntu3.15
    
    Ubuntu 12.04 LTS:
      apport                          2.0.1-0ubuntu17.10
    
    In general, a standard system update will make all the necessary changes.
