CVE-2010-4262: Buffer Overflow
A stack-based buffer overflow flaw was found in the way Xfig processed certain FIG images. A remote attacker could create a FIG image with specially-crafted color definition, and trick the local, unsuspecting user into opening it, which could lead to xfig executable crash or, potentially, arbitrary code execution with the privileges of the user running the executable.
