Secunia - Advisories - Winamp Skin File Arbitrary Code Execution Vulnerability

It appears that if you use WinAmp, you are in danger - this is a pretty nasty vulnerability. I don't use it, but if I did, I would stop immediately until they fixed this problem! If the winamp icom is in your taskbar (lower right corner) you need to click it, get into the options, system options, and disable it from running on startup!

By the way, this thing automatically runs on startup as default, so if you have winamp installed and haven't turned that off, it is likely running, and you are vulnerable.
