    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 17.04
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    GDK-PixBuf could be made to crash or run programs as your login if it
    opened a specially crafted file.
    
    Software Description:
    - gdk-pixbuf: GDK Pixbuf library
    
    Details:
    
    It was discovered that the GDK-PixBuf library did not properly handle
    certain jpeg images. If an user or automated system were tricked into
    opening a specially crafted jpeg file, a remote attacker could use this
    flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or
    possibly execute arbitrary code. (CVE-2017-2862)
    
    It was discovered that the GDK-PixBuf library did not properly handle
    certain tiff images. If an user or automated system were tricked into
    opening a specially crafted tiff file, a remote attacker could use this
    flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or
    possibly execute arbitrary code. (CVE-2017-2870)
    
    Ariel Zelivansky discovered that the GDK-PixBuf library did not
    properly handle printing certain error messages. If an user or
    automated system were tricked into opening a specially crafted image
    file, a remote attacker could use this flaw to cause GDK-PixBuf to
    crash, resulting in a denial of service. (CVE-2017-6311)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 17.04:
      libgdk-pixbuf2.0-0              2.36.5-3ubuntu0.2
    
    Ubuntu 16.04 LTS:
      libgdk-pixbuf2.0-0              2.32.2-1ubuntu1.3
    
    Ubuntu 14.04 LTS:
      libgdk-pixbuf2.0-0              2.30.7-0ubuntu1.7
    
    After a standard system update you need to restart your session to make
    all the necessary changes.
