MPlayer is an open source media player with support for many operating systems.
MPlayer does not properly validate the contents of Synchronized Accessible Media Interchange (SAMI) caption files. If a video references a malformed SAMI file, it may trigger a stack overflow.
While no official updated binary release has been made, the issue has been corrected in the SVN sourcecode repository as of r33471. Please rebuild MPlayer from source using r33471 or later.
This exploit has been tested against MPlayer Project SMPlayer 0.6.9 on Windows XP SP3 English (DEP OptIn) with KB959426.
