WinAmp flayed by skins attack
Exploit circulating for unpatched vuln
Updated A serious security flaw in NullSoft's popular WinAmp  player opens the door for crackers to seize control of vulnerable systems.
The vulnerability  stems from a flaw in how the player processes Winamp skin zip files. This flaw means WinAmp users induced to visit a maliciously constructed website could find their PCs rooted. The vulnerability has been confirmed on a fully patched system with WinAmp 5.04 using Internet Explorer 6.0 on Microsoft Windows XP SP1. WinAmp 3.x users are also potentially in peril. And that's not the worst of it. The bug, reported by the K-OTik.COM Security Survey Team, is reportedly being actively exploited in the wild.
Update - 31 Aug
Nullsoft has released an updated version of Winamp that addresses the vulnerability. You can download Wainamp version 5.5 here . ®
