More information:

Sebastien Helleu discovered that an error in the handling of color codes in the weechat IRC client could cause an out-of-bounds read of an internal color array. This can be used by an attacker to crash user clients via a crafted PRIVMSG command.

The weechat version in the oldstable distribution (etch) is not affected by this problem.

For the stable distribution (lenny), this problem has been fixed in version 0.2.6-1+lenny1.

For the testing distribution (squeeze), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in version 0.2.6.1-1.

We recommend that you upgrade your weechat packages.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
