=====================================================================

1. Summary:

An updated squirrelmail package that resolves various security issues is
now available for Red Hat Enterprise Linux 3, 4 and 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - noarch
Red Hat Desktop version 3 - noarch
Red Hat Enterprise Linux ES version 3 - noarch
Red Hat Enterprise Linux WS version 3 - noarch
Red Hat Enterprise Linux AS version 4 - noarch
Red Hat Enterprise Linux Desktop version 4 - noarch
Red Hat Enterprise Linux ES version 4 - noarch
Red Hat Enterprise Linux WS version 4 - noarch
RHEL Desktop Workstation (v. 5 client) - noarch
Red Hat Enterprise Linux (v. 5 server) - noarch

3. Description:

SquirrelMail is an easy-to-configure, standards-based, webmail package
written in PHP. It includes built-in PHP support for the IMAP and SMTP
protocols, and pure HTML 4.0 page-rendering (with no JavaScript required)
for maximum browser-compatibility, strong MIME support, address books, and
folder manipulation.

Ivan Markovic discovered a cross-site scripting (XSS) flaw in SquirrelMail
caused by insufficient HTML mail sanitization. A remote attacker could send
a specially-crafted HTML mail or attachment that could cause a user's Web
browser to execute a malicious script in the context of the SquirrelMail
session when that email or attachment was opened by the user.
(CVE-2008-2379)

It was discovered that SquirrelMail allowed cookies over insecure
connections (ie did not restrict cookies to HTTPS connections). An attacker
who controlled the communication channel between a user and the
SquirrelMail server, or who was able to sniff the user's network
communication, could use this flaw to obtain the user's session cookie, if
a user made an HTTP request to the server. (CVE-2008-3663)

Note: After applying this update, all session cookies set for SquirrelMail
sessions started over HTTPS connections will have the "secure" flag set.
That is, browsers will only send such cookies over an HTTPS connection. If
needed, you can revert to the previous behavior by setting the
configuration option "$only_secure_cookies" to "false" in SquirrelMail's
/etc/squirrelmail/config.php configuration file.

Users of squirrelmail should upgrade to this updated package, which
contains backported patches to correct these issues.

4. Solution:

Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

464183 - CVE-2008-3663 squirrelmail: session hijacking - secure flag not set for HTTPS-only cookies
473877 - CVE-2008-2379 squirrelmail: XSS issue caused by an insufficient html mail sanitation
