Default Moderate: squirrelmail security update

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

================================================== ===================
Red Hat Security Advisory

Synopsis: Moderate: squirrelmail security update
Advisory ID: RHSA-2009:0010-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-0010.html
Issue date: 2009-01-12
CVE Names: CVE-2008-2379 CVE-2008-3663
================================================== ===================

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

1. Summary:

An updated squirrelmail package that fixes several security issues is now
available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - noarch
Red Hat Enterprise Linux (v. 5 server) - 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

3. Description:

SquirrelMail is a standards-based webmail package written in PHP.

A cross-site scripting (XSS) flaw was found in the way SquirrelMail
performed the sanitization of HTML style tag content. A remote attacker
could use this flaw to send a specially-crafted Multipurpose Internet Mail
Extensions (MIME) message that, when opened by a victim, would lead to
arbitrary web script execution in the context of their SquirrelMail
session. (CVE-2011-2023)

Multiple cross-site scripting (XSS) flaws were found in SquirrelMail. A
remote attacker could possibly use these flaws to execute arbitrary web
script in the context of a victim's SquirrelMail session. (CVE-2010-4555)

An input sanitization flaw was found in the way SquirrelMail handled the
content of various HTML input fields. A remote attacker could use this
flaw to alter user preference values via a newline character contained in
the input for these fields. (CVE-2011-2752)

It was found that the SquirrelMail Empty Trash and Index Order pages did
not protect against Cross-Site Request Forgery (CSRF) attacks. If a remote
attacker could trick a user, who was logged into SquirrelMail, into
visiting a specially-crafted URL, the attacker could empty the victim's
trash folder or alter the ordering of the columns on the message index
page. (CVE-2011-2753)

SquirrelMail was allowed to be loaded into an HTML sub-frame, allowing a
remote attacker to perform a clickjacking attack against logged in users
and possibly gain access to sensitive user data. With this update, the
SquirrelMail main frame can only be loaded into the top most browser frame.
(CVE-2010-4554)

A flaw was found in the way SquirrelMail handled failed log in attempts. A
user preference file was created when attempting to log in with a password
containing an 8-bit character, even if the username was not valid. A
remote attacker could use this flaw to eventually consume all hard disk
space on the target SquirrelMail server. (CVE-2010-2813)

A flaw was found in the SquirrelMail Mail Fetch plug-in. If an
administrator enabled this plug-in, a SquirrelMail user could use this flaw
to port scan the local network the server was on. (CVE-2010-1637)

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 all previously-released errata
relevant to your system have been applied.
