Yderligere oplysninger:

Sebastien Helleu opdagede at en fejl i håndteringen af farvekoder i IRC-klienten weechat, kunne forårsage læsning uden for grænserne i et internt farvearray. Det kunne udnyttes af en angriber til at få brugerklienter til at gå ned ved hjælp af en særligt fabrikeret PRIVMSG-kommando.

Versionen af weechat i den gamle stabile distribution (etch) er ikke påvirket af dette problem.

I den stabile distribution (lenny), er dette problem rettet i version 0.2.6-1+lenny1.

I distribution testing (squeeze), vil dette problem snart blive rettet.

I den ustabile distribution (sid), er dette problem rettet i version 0.2.6.1-1.

Vi anbefaler at du opgraderer dine weechat-pakker.

Rettet i:

Debian GNU/Linux 5.0 (lenny)
