    Ubuntu Security Notice USN-2489-1
    February 03, 2015
    
    unzip vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.10
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    
    Details:
    
    Michal Zalewski discovered that unzip incorrectly handled certain
    malformed zip archives. If a user or automated system were tricked into
    processing a specially crafted zip archive, an attacker could possibly
    execute arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      unzip                           6.0-12ubuntu1.2
    
    Ubuntu 14.04 LTS:
      unzip                           6.0-9ubuntu1.2
    
    Ubuntu 12.04 LTS:
      unzip                           6.0-4ubuntu2.2
    
    Ubuntu 10.04 LTS:
      unzip                           6.0-1ubuntu0.2
    
    In general, a standard system update will make all the necessary changes.
