> *** {01.31.023} Linux - Linux kernel IRC/DCC masquerading helper
>                 vulnerability
> 
> A bug was found in the various IRC DCC/CTCP masquerading helper modules
> shipped with the various Linux kernels. It's possible for a remote
> attacker/Web site to open arbitrary ports on a masquerading Linux
> firewall by "spoofing" the DCC/CTCP connect commands. This results
> in the IRC helper module processing the commands and opening ports
> in an effort to allow the incoming DCC/CTCP session.
> 
> This vulnerability has been confirmed. A patch is available at:
