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.
