CVE reference:CVE-2006-5567


Description:
Two vulnerabilities have been discovered in Winamp, which can be exploited by malicious people to compromise a user's system.

1) An integer overflow in the Ultravox protocol handler during processing of the "ultravox-max-msg" header can be exploited to cause a heap-based buffer overflow via a specially crafted Ultravox server response.

2) An integer overflow during the parsing of certain Lyrics3 tags can be exploited to cause a heap-based buffer overflow via a specially crafted MP3 file.

The vulnerabilities are confirmed in version 5.3. Versions 2.666 through 5.3 are reportedly vulnerable.

Solution:
Update to version 5.31.
