    Ubuntu Security Notice USN-1153-1
    June 16, 2011
    
    libxml2 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.04
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 LTS
    
    Summary:
    
    libxml2 could be made to crash or run programs as your login if it opened a
    specially crafted file.
    
    Software Description:
    - libxml2: GNOME XML library
    
    Details:
    
    Chris Evans discovered that libxml2 incorrectly handled memory allocation.
    If an application using libxml2 opened a specially crafted XML file, an
    attacker could cause a denial of service or possibly execute code as the
    user invoking the program.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.04:
      libxml2                         2.7.8.dfsg-2ubuntu0.1
    
    Ubuntu 10.10:
      libxml2                         2.7.7.dfsg-4ubuntu0.2
    
    Ubuntu 10.04 LTS:
      libxml2                         2.7.6.dfsg-1ubuntu1.2
    
    Ubuntu 8.04 LTS:
      libxml2                         2.6.31.dfsg-2ubuntu1.6
    
    After a standard system update you need to restart your session to make
    all the necessary changes.
