[GLSA-200603-09] SquirrelMail: Cross-site scripting and IMAP command injection

Vulnerability Assessment Summary
SquirrelMail: Cross-site scripting and IMAP command injection

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200603-09
(SquirrelMail: Cross-site scripting and IMAP command injection)

SquirrelMail does not validate the right_frame parameter in
webmail.php, possibly permiting 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 permiting 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.

Solution:
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.
