ned has discovered a vulnerability in Icecast, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an out-of-bounds read error within the web interface when handling Basic Authorization requests. This can be exploited to crash the application by passing a specially crafted, overly long string (about 3000 bytes) in a "Authorization:" header.
The vulnerability has been confirmed in version 2.0.0 for Windows. Other versions may also be affected.
