imapd4r1 v12.264 exploit

The imap daemon shipped with the newest redhat has a security hole, which allows the intruder to get shell access to the mail account.

Privledges seems to be dropped, but, anyway, it's nice way to get shell access to mail account, maybe grab some data from memory etc. I believe both imap and ipopd packages need code security audit.
