"Multiple vulnerabilities were discovered in libgd2, a graphics 
library :

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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
