Issue date:	2008-02-21
CVE Names:	CVE-2008-0553 CVE-2007-5137 CVE-2007-5378

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.
