update to 1.4.17 fixes XSS issue caused by an insufficient html mail sanitation

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update brings squirrelmail to version 1.4.10a, fixing a previous regression in cookie handling (novell bug 446400) and a XSS problem (CVE-2008-2379).

Insufficient input checks could allow remote attackers to conduct a cross site scripting (XSS) attack (CVE-2008-2379).

Ivan Markovic discovered that SquirrelMail, a webmail application, did not sufficiently sanitise incoming HTML email, allowing an attacker to perform cross site scripting through sending a malicious HTML email.

The remote Redhat Enterprise Linux 4 / 5 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2009:0010 advisory.

    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.

Squirrelmail team reports :

An issue was fixed that allowed an attacker to send specially- crafted hyperlinks in a message that could execute cross-site scripting (XSS) when the user viewed the message in SquirrelMail.

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.
