Description Vincent Danen 2010-10-29 20:07:06 UTC
This is an old issue that is not a problem with current Fedora releases (due to providing xcftools 1.0.7), however gnome-xcf-thumbnailer embedds what looks like xcftools 1.0.4 (vulnerable version) or earlier, as reported to Debian [1].  A patch [2] exists in the original Debian bug report [3] to correct the flaw.  The MITRE entry for this flaw follows:

Stack-based buffer overflow in the flattenIncrementally function in flatten.c in xcftools 1.0.4, as reachable from the (1) xcf2pnm and (2) xcf2png utilities, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted image that causes a conversion to a location "above or to the left of the canvas." NOTE: some of these details are obtained from third party information.
