It was discovered that there was a stack consumption vulnerability in the libgd2 graphics library which allowed remote attackers to cause a denial of service via a crafted imagefilltoborder call.

For Debian 7 ‘Wheezy’, this issue has been fixed in libgd2 version 2.0.36~rc1~dfsg-6.1+deb7u3.

We recommend that you upgrade your libgd2 packages.

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.
