Less critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
now_playing.rb for weechat 0.x
http://secunia.com/product/15317/

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

The vulnerability is caused due to now_playing.rb not correctly
filtering id3 tags before sending them to weechat. 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 0.1. Other versions may also
be affected.

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