    Ubuntu Security Notice USN-1587-1
    September 27, 2012
    
    libxml2 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 LTS
    
    Summary:
    
    Applications using libxml2 could be made to crash or run programs as your
    login if they opened a specially crafted file.
    
    Software Description:
    - libxml2: GNOME XML library
    
    Details:
    
    Juri Aedla discovered that libxml2 incorrectly handled certain memory
    operations. If a user or application linked against libxml2 were tricked
    into opening a specially crafted XML file, an attacker could cause the
    application to crash or possibly execute arbitrary code with the privileges
    of the user invoking the program.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      libxml2                         2.7.8.dfsg-5.1ubuntu4.2
    
    Ubuntu 11.10:
      libxml2                         2.7.8.dfsg-4ubuntu0.4
    
    Ubuntu 11.04:
      libxml2                         2.7.8.dfsg-2ubuntu0.5
    
    Ubuntu 10.04 LTS:
      libxml2                         2.7.6.dfsg-1ubuntu1.6
    
    Ubuntu 8.04 LTS:
      libxml2                         2.6.31.dfsg-2ubuntu1.10
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
