Technical Description

Multiple vulnerabilities have been identified in Winamp, which could be exploited by remote attackers to cause a denial of service or take complete control of an affected system. These issues are caused by buffer overflow errors in "in_mp3.dll" when constructing stream titles while parsing Ultravox streaming metadata, which could be exploited by remote attackers to execute arbitrary code via overly long "<artist>" and "<name>" tag values in the <metadata> section.

An integer overflow has also been reported in the "gen_ff.dll" library when parsing a specially crafted ".maki" file, which could be exploited by attackers to execute arbitrary code by tricking a user into loading a malicious skin.

Affected Products
