Winamp blighted by bug brace

Lament over Ultravox vuln

A brace of bugs in Winamp pose a serious security risk for users of the popular media player package, security watchers warn.

The buffer overflow-related flaws in Winamp 5.x create a means for hackers to take over vulnerable systems. Flaws in a library (in_mp3.dll) involved in parsing Ultravox streaming metadata open up the door to abuse, security notification firm Secunia warns. "These boundary errors can be exploited to cause stack-based buffer overflows via overly long '<artist>' and '<name>' tag values in the <metadata> section," it explains.

Secunia, whose researchers discovered the bugs, adds that successful exploitation allows the execution of arbitrary code. The vulnerabilities have been confirmed in versions 5.21, 5.5, and 5.51 of Winamp. Other versions may also be affected.

Users are advised to upgrade to Winamp version 5.52. Winamp is developed by Nullsoft, a subsidiary of AOL Music. ®
