Description Paul Slinski 2004-05-13 07:01:35 UTC
A vulnerability in Icecast, 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.

Reproducible: Always
Steps to Reproduce:

Icecast 2.0.1 has been released to plug the hole

See for the advisory.

Like the Xiph guys say, "this release contains ONLY the fix for this issue" so it shouldn't be a painful upgrade.

Sound guys, could you bump the ebuild to 2.0.1 ?
