  - CVE-2014-2497
    The gdImageCreateFromXpm() function would try to
    dereference a NULL pointer when reading an XPM file with
    a special color table. This could allow remote attackers
    to cause a denial of service (crash) via crafted XPM
    files.

  - CVE-2014-9709
    Importing an invalid GIF file using the
    gdImageCreateFromGif() function would cause a read
    buffer overflow that could allow remote attackers to
    cause a denial of service (crash) via crafted GIF files."
