A vulnerability has been reported in Winamp, which can be exploited by malicious people to compromise a user's system.
The problem is caused due to insufficient restrictions on Winamp skin zip files (.wsz). This can e.g. be exploited by a malicious website using a specially crafted Winamp skin to place and execute arbitrary programs. With Internet Explorer this can be done without user interaction.
The vulnerability has been confirmed on a fully patched system with Winamp 5.04 using Internet Explorer 6.0 on Microsoft Windows XP SP1.
