|Potential security issue with people adding a trailing '.' to your domain
||[Jul. 15th, 2009|11:05 pm]
If you have domain forwarding enabled, a user can take control of www.sitename.com. (note the trailing dot) and possibly get ahold of the users master cookie, as well as some other pretty vile things.
Adding $host =~ s/\.$//; on line 256 of cgi-bin/Apache/LiveJournal.pm should correct this issue.
