Tk is a graphical toolkit for the Tcl scripting language. 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.
