A certain Red Hat patch for SquirrelMail 1.4.8 sets the same SQMSESSID cookie value for all sessions, which allows remote authenticated users to access other users' folder lists and configuration data in opportunistic circumstances by using the standard webmail.php interface. NOTE: this vulnerability exists because of an incorrect fix for CVE-2008-3663.

From Red Hat Security Advisory 2009:0057 :

An updated squirrelmail package that fixes a security issue is now available for Red Hat Enterprise Linux 3, 4 and 5.

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

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.

The Red Hat SquirrelMail packages provided by the RHSA-2009:0010 advisory introduced a session handling flaw. Users who logged back into SquirrelMail without restarting their web browsers were assigned fixed session identifiers. A remote attacker could make use of that flaw to hijack user sessions. (CVE-2009-0030)

SquirrelMail users should upgrade to this updated package, which contains a patch to correct this issue. As well, all users who used affected versions of SquirrelMail should review their preferences.

This update brings the Mozilla Firefox 3.5 webbrowser to version 3.5.3, the Mozilla XULRunner 1.9.0 engine to the 1.9.0.14 stable release, and the Mozilla XULRunner 1.9.1 engine to the 1.9.1.3 stable release.

It also fixes various security issues: MFSA 2009-47 / CVE-2009-3069 / CVE-2009-3070 / CVE-2009-3071 / CVE-2009-3072 / CVE-2009-3073 / CVE-2009-30 / CVE-2009-3075: Mozilla developers and community members identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products.
Some of these crashes showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code.

MFSA 2009-48 / CVE-2009-3076: Mozilla security researcher Jesse Rudermanreported that when security modules were added or removed via pkcs11.addmodule or pkcs11.deletemodule, the resulting dialog was not sufficiently informative. Without sufficient warning, an attacker could entice a victim to install a malicious PKCS11 module and affect the cryptographic integrity of the victim's browser. Security researcher Dan Kaminsky reported that this issue had not been fixed in Firefox 3.0 and that under certain circumstances pkcs11 modules could be installed from a remote location. Firefox 3.5 releases are not affected.

MFSA 2009-49 / CVE-2009-3077: An anonymous security researcher, via TippingPoint's Zero Day Initiative, reported that the columns of a XUL tree element could be manipulated in a particular way which would leave a pointer owned by the column pointing to freed memory. An attacker could potentially use this vulnerability to crash a victim's browser and run arbitrary code on the victim's computer.

MFSA 2009-50 / CVE-2009-3078: Security researcher Juan Pablo Lopez Yacubian reported that the default Windows font used to render the locationbar and other text fields was improperly displaying certain Unicode characters with tall line-height. In such cases the tall line-height would cause the rest of the text in the input field to be scrolled vertically out of view. An attacker could use this vulnerability to prevent a user from seeing the URL of a malicious site. Corrie Sloot also independently reported this issue to Mozilla.

MFSA 2009-51 / CVE-2009-3079: Mozilla security researcher moz_bug_r_a4 reported that the BrowserFeedWriter could be leveraged to run JavaScript code from web content with elevated privileges. Using this vulnerability, an attacker could construct an object containing malicious JavaScript and cause the FeedWriter to process the object, running the malicious code with chrome privileges. Thunderbird does not support the BrowserFeedWriter object and is not vulnerable in its default configuration. Thunderbird might be vulnerable if the user has installed any add-on which adds a similarly implemented feature and then enables JavaScript in mail messages. This is not the default setting and we strongly discourage users from running JavaScript in mail.
