Winamp .m3u and .pls file name buffer overflow
| winamp-playlist-filename-bo (24361) |  High Risk |
Description:
Winamp is vulnerable to a stack-based buffer overflow, caused by improper bounds checking of file names within a playlist. By creating a malicious .pls or .m3u file containing an overly long file name path, a remote attacker could overflow a buffer and execute arbitrary code on the system, once a victim loads the malicious playlist. An attacker could exploit this vulnerability by hosting the malicious .pls or .m3u file on a Web page.
Platforms Affected:
- Nullsoft, Winamp 5.11
- Nullsoft, Winamp 5.12
Remedy:
Upgrade to the latest version of Winamp (5.13 or later), available from the Winamp Web page. See References.
Consequences:
