[GLSA-200501-39] SquirrelMail: Multiple vulnerabilities

Vulnerability Assessment Summary
SquirrelMail: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
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 (CVE-2005-0075) and in webmail.php (CVE-2005-0103).
Insufficient escaping of integers in webmail.php
(CVE-2005-0104).

Impact

By sending a specially-crafted URL, a possible hacker 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.

Workaround

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.

Solution:
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.
