Who is Vulnerable?
Vulnerability Description	VLC media player is an open source multimedia player. It can play many audio and video formats (MPEG, DivX, ogg, Wave etc.) as well as various streaming protocols. It is highly portable and available for multiple platforms. Support for various formats is implemented in the form of plugins bundled with the player as shared object or windows DLL files. There exists a vulnerability in VideoLAN VLC Media Player. The vulnerability is due to an integer overflow during the calculation of the size of a heap buffer. An unauthenticated remote attacker could exploit this vulnerability by enticing a user to play a specially crafted Wave/WAV file. Successful exploitation would cause a heap buffer overflow allowing the attacker to execute arbitrary code on the vulnerable system. In an attack case where code injection is not successful, VideoLAN VLC client application will terminate unexpectedly. In a more sophisticated attack scenario where code injection is successful, the behaviour of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user. The affected application would also most likely stop functioning as a result of such an attack.
