CRITICAL:
Less critical

IMPACT:
Security Bypass

WHERE:
From remote

SOFTWARE:
Disrok for XChat 1.x
http://secunia.com/product/15320/

DESCRIPTION:
Wouter Coekaerts has reported a vulnerability in Disrok, which can be
exploited by malicious people to bypass certain security
restrictions.

The vulnerability is caused due to Disrok not correctly filtering id3
tags before sending them to XChat. This can be exploited to e.g. send
arbitrary commands to a server by tricking a user into playing and
announcing a specially crafted MP3 file.

The vulnerability is reported in version 1.0. Other versions may also
be affected.

SOLUTION:
Do not play and announce untrusted audio files. Use another product.
