Description Vincent Danen 2012-03-14 17:53:38 UTC
It was reported [1] that an integer overflow in GNU Gnash's GnashImage::size() method could be exploited to cause a heap-based buffer overflow when opening certain specially-crafted SWF files.  If a user were tricked into opening a malicious SWF file it cause cause Gnash to crash or, possibly, execute arbitrary code with the permissions of the user running Gnash.

The flaw was reported in 0.8.10 and is fixed in git [2].
