[ISSUE]
WPkontakt is the another Polish instant messenger. The problem is similiar
to the problems revealed in GG or Tlen.pl - parsing error leading to the
remote script execution.
[DETAILS]
Parsing error while parsing en email addresses allows us to inject
javascript code like this:
test@"style="background-image:url(javascript:alert(%22You%20are%20owned!%22>))".wp.pl
The code will execute in Internet Zone.
[SOLUTION]
Please upgrade to the newest version (3.0.1p1)
