The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200501-39
(SquirrelMail: Multiple vulnerabilities)
SquirrelMail fails to properly sanitize certain strings when
decoding specially-crafted strings, which can lead to PHP file
inclusion and XSS.
Insufficient checking of incoming URLs
in prefs.php (CAN-2005-0075) and in webmail.php (CAN-2005-0103).
Insufficient escaping of integers in webmail.php
By sending a specially-crafted URL, an attacker can execute
arbitrary code from the local system with the permissions of the web
server. Furthermore by enticing a user to load a specially-crafted URL,
it is possible to display arbitrary remote web pages in Squirrelmail's
frameset and execute arbitrary scripts running in the context of the
victim's browser. This could lead to a compromise of the user's webmail
account, cookie theft, etc.
The arbitrary code execution is only possible with
'register_globals' set to 'On'. Gentoo ships PHP with
'register_globals' set to 'Off' by default. There are no known
workarounds for the other issues at this time.

All SquirrelMail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=mail-client/squirrelmail-1.4.4'
Note: Users with the vhosts USE flag set should manually use
webapp-config to finalize the update.
