Description

An input validation flaw was discovered in Tk's GIF image handling. A code-size value read from a GIF image was not properly validated before being used, leading to a buffer overflow. A specially crafted GIF file could use this to cause a crash or, potentially, execute code with the privileges of the application using the Tk graphical toolkit. (CVE-2008-0553)

A buffer overflow flaw was discovered in Tk's animated GIF image handling. An animated GIF containing an initial image smaller than subsequent images could cause a crash or, potentially, execute code with the privileges of the application using the Tk library. (CVE-2007-5137)
