TITLE:
Winamp Ultravox Streaming Metadata Parsing Buffer Overflows

SECUNIA ADVISORY ID:
SA27865

VERIFY ADVISORY:
http://secunia.com/advisories/27865/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
Winamp 5.x
http://secunia.com/product/3021/

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

The vulnerabilities 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.

The vulnerabilities are confirmed in versions 5.21, 5.5, and 5.51.
Other versions may also be affected.

SOLUTION:
Update to version 5.52.
