    cups vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    
    Summary:
    
    CUPS could be made to expose sensitive information, leading to privilege
    escalation.
    
    Software Description:
    - cups: Common UNIX Printing System(tm)
    
    Details:
    
    Francisco Alonso discovered that the CUPS web interface incorrectly
    validated permissions on rss files. A local attacker could possibly use
    this issue to bypass file permissions and read arbitrary files, possibly
    leading to a privilege escalation.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      cups                            1.7.2-0ubuntu1.1
    
    Ubuntu 12.04 LTS:
      cups                            1.5.3-0ubuntu8.4
    
    Ubuntu 10.04 LTS:
      cups                            1.4.3-1ubuntu1.12
    
    In general, a standard system update will make all the necessary changes.
