    Ubuntu Security Notice USN-1120-1

    tiff vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    
    Summary:
    
    The TIFF library could be made to run programs as your login if it opened a
    specially crafted file.
    
    Software Description:
    - tiff: TIFF manipulation and conversion tools
    
    Details:
    
    It was discovered that the TIFF library incorrectly handled certain JPEG
    data. If a user or automated system were tricked into opening a specially
    crafted TIFF image, a remote attacker could execute arbitrary code with
    user privileges, or crash the application, leading to a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 10.10:
      libtiff4                        3.9.4-2ubuntu0.4
    
    Ubuntu 10.04 LTS:
      libtiff4                        3.9.2-2ubuntu0.7
    
    After a standard system update you need to restart your session to make
    all the necessary changes.
