Synopsis
========
SquirrelMail is vulnerable to several cross-site scripting
vulnerabilities and IMAP command injection.
Background
==========
SquirrelMail is a webmail package written in PHP. It supports IMAP and
SMTP protocols.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 mail-client/squirrelmail < 1.4.6 >= 1.4.6
Description
===========
SquirrelMail does not validate the right_frame parameter in
webmail.php, possibly allowing frame replacement or cross-site
scripting (CVE-2006-0188). Martijn Brinkers and Scott Hughes discovered
that MagicHTML fails to handle certain input correctly, potentially
leading to cross-site scripting (only Internet Explorer,
CVE-2006-0195). Vicente Aguilera reported that the
sqimap_mailbox_select function did not strip newlines from the mailbox
or subject parameter, possibly allowing IMAP command injection
(CVE-2006-0377).
Impact
======
By exploiting the cross-site scripting vulnerabilities, an attacker can
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. A remote attacker could exploit the IMAP command
injection to execute arbitrary IMAP commands on the configured IMAP
server.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All SquirrelMail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.6"
Note: Users with the vhosts USE flag set should manually use
webapp-config to finalize the update.
