Debian DLA-189-1 : libgd2 security update
Medium Nessus Plugin ID 82646
SynopsisThe remote Debian host is missing a security update.
DescriptionMultiple vulnerabilities were discovered in libgd2, a graphics library :
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.
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.
SolutionUpgrade the affected packages.
