4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in Winamp, which
can be exploited by malicious people to compromise a user's system.

The vulnerablities are caused due to boundary errors in in_mp3.dll
within the construction of stream titles when parsing Ultravox
streaming metadata. This can be exploited to cause stack-based buffer
overflows via overly long "<artist>" and "<name>" tag values in the
<metadata> section.

Successful exploitation allows execution of arbitrary code.

5) Solution 

Update to version 5.52.
