Description Tomas Hoger 2008-02-05 03:48:15 EST
tk GIF handling code is based on the same code as used by gd and SDL_image and
is affected by the overflow known as CVE-2006-4484 and CVE-2007-6697.

ReadImage function in tkImgGIF.c does not properly check the value of
initialCodeSize value read from GIF image before using it as upper bound during
the initialization of append array.  This can result in stack buffer overflow.

Upstream fix:
http://tktoolkit.cvs.sourceforge.net/tktoolkit/tk/generic/tkImgGIF.c?r1=1.40&r2=1.41

This is expected to be included in upstream tk version 8.5.1.

Related issues:
CVE-2006-4484 (gd), CVE-2007-6697 (SDL_image), CVE-2008-0554 (netpbm)
