<p>
SquirrelMail is a webmail package written in PHP. It supports IMAP
and SMTP protocols.
</p>
</background>
<description>
<p>
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).
</p>
</description>
<impact type="low">
<p>
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.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All SquirrelMail users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=mail-client/squirrelmail-1.4.6&quot;</code>
<p>
Note: Users with the vhosts USE flag set should manually use
webapp-config to finalize the update.
