Description


A vulnerability has been discovered in VLC Media Player, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the application loading libraries (e.g. wintab32.dll) in an insecure manner. This can be exploited to load arbitrary libraries by tricking a user into e.g. opening an MP3 file located on a remote WebDAV or SMB share.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in version 1.1.3 for Windows. Other versions may also be affected.


Solution:
Update to version 1.1.4.

VLC 1.1.4 is available at the VideoLan web site. PCI doesn't think it corrects the vulnerability. Does it?

According to these articles (http://isc.sans.edu/diary.html?storyid=9445 and http://www.h-online.com/security/news/item/Attacke...) there are DLL vulnerabilities in numerous applications, not just VLC player (e.g. Firefox, see http://secunia.com/community/forum/thread/show/529...). VLC player version 1.1.4 is one of the first programs, where this problem is fixed.
