Secunia has found a flaw in the VLC Media Player that could allow an attacker to gain control of someone's PC. The problem, which Secunia ranks as "highly critical," affects version 0.8.6h on Windows. Secunia said in an advisory that version 0.8.6i should be released soon.
The flaw is an integer overflow error, which can be exploited to cause a heap-based buffer overflow, a type of problem in how the program allocates memory. Secunia said it can be exploited by creating a specially-crafted ".WAV" sound file, which would the allow a hacker to run other code on the PC.
VLC Media Player is a free, open-source program released under the GNU General Public License by the VideoLAN project . The player can handle video files in MPEG-1, MPEG-2, MPEG-4, DivX, MP3, and OGG formats, among others.
