Description Lubomir Kundrak 2007-09-04 19:41:08 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2007-3476 to the following vulnerability:

Array index error in gd_gif_in.c in the GD Graphics Library (libgd) before 2.0.35 allows user-assisted remote attackers to cause a denial of service (crash and heap corruption) via large color index values in crafted image data, which results in a segmentation fault.

Same patch as above, but directly in libgd CVS repo:

Comment 4 Tomas Hoger 2008-02-11 18:07:15 UTC

This issue does not affect versions of gd as shipped with Red Hat Enterprise
Linux 2.1 and 3, as those versions do not offer GIF image type support.
