Signature Detail

HTTP: WinAmp Ultravox ultravox-max-msg Header Buffer Overflow

This signature detects attempts to exploit a known vulnerability in WinAmp Ultravox. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the client.

Extended Description

Winamp is prone to multiple Ultravox-related remote heap-based buffer-overflow vulnerabilities because the application fails to properly bounds-check user-supplied input before copying it into an insufficiently sized memory buffer. Successfully exploiting these issues allows remote attackers to execute arbitrary machine code in the context of the vulnerable application. This will facilitate the remote compromise of affected computers. To exploit these issues, attackers would have to coerce unsuspecting users to connect to a malicious server with the vulnerable application. This may be accomplished by having users follow a malicious URI or by embedding malicious data in a playlist file.
