4) Description of Vulnerability
Secunia Research has discovered three vulnerabilities in Winamp, which
can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused by boundary errors in the Module
Decoder Plug-in (IN_MOD.DLL) when parsing instrument definitions and
can be exploited to cause heap-based buffer overflows via a specially
