Winamp .m3u and .pls playlist .wma extension buffer overflow
| winamp-wma-ext-bo (24417) |  High Risk |
Description:
Winamp is vulnerable to a buffer overflow, caused by improper validation of .m3u and .pls files. By creating a malicious .pls or .m3u file containing a reference to a file with the .wma extension, a remote attacker could overflow a buffer and cause Winamp to crash or 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.
