This is signature will detect attempt to exploit a buffer overflow exploit in VLC media player SMB URI.
VLC Media Player is a media player for a number of platforms. The application has a web-based interface.
The application is prone to a remote stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Specifically, the issue affects the 'Win32AddConnection()' function of 'modules/access/smb.c' and arises when handling a long 'smb://' URI.
A remote attacker may exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause denial-of-service conditions.
VLC Media Player 0.9.9 through 1.0.1 for Windows are vulnerable; other versions may also be affected.
A vendor fix is available in the GIT repository. Please see the references for details.
