- Security database references:
- In the Debian bugtracking system: Bug 744719.

- More information:
Multiple 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.
For the stable distribution (wheezy), these problems have been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u1.
For the upcoming stable distribution (jessie), these problems have been fixed in version 2.1.0-5.
For the unstable distribution (sid), these problems have been fixed in version 2.1.0-5.
We recommend that you upgrade your libgd2 packages.
