A vulnerability was reported in Winamp. A remote user can cause arbitrary code to be executed on the target system.|
A remote user can create a specially crafted '.m3u' file that, when loaded by the target user, will trigger a buffer overflow and execute arbitrary code. The code will run with the privileges of the target user.
The vulnerability occurs when the target user pauses or stops the file and the title of the program being played is reset, triggering a buffer overflow.
The vendor was notified on February 13, 2006.
