The vulnerability is located in the VLC component responsible for playing ASF (Advanced Streaming Format) video files, VideoLAN, the non-profit organization that develops the media player, said in a security advisory published on its website. Vulnerability research and management firm Secunia rated the flaw as highly critical and said its successful exploitation could allow the execution of arbitrary code. The flaw can be exploited by tricking a user into opening a specially crafted ASF file.
VideoLAN advises users to refrain from opening files from untrusted locations and to disable the VLC browser plug-ins until the issue is patched. By default, VLC installs plug-ins for Mozilla Firefox, Internet Explorer, Google Chrome, Apple Safari, Opera and Konqueror. The plug-ins allow the playback of video files embedded into Web pages.
An alternative solution is to manually delete the vulnerable libasf_plugin.dll file from the VLC installation directory, VideoLAN said. This will disable the software's ability to play ASF videos until a patched version of the file is reinstalled during a software update...
