SynopsisThe remote Debian host is missing a security update.
DescriptionIt was discovered that invalid color causes stack exhaustion by recursive call to function gdImageFillToBorder when the image used is truecolor.
The vulnerability can be exploited through php5 which uses system's libgd2 library through the imagefilltoborder() PHP function to cause denial of service (stack overflow) and possibly have unspecified other impact.
For Debian 7 'Wheezy', these problems have been fixed in version 2.0.36~rc1~dfsg-6.1+deb7u7.
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.
SolutionUpgrade the affected packages.
