Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated SeaMonkey packages that fix two security issues are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having critical 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.

SeaMonkey is an open source web browser, email and newsgroup client, IRC chat client, and HTML editor.

A flaw was found in the way SeaMonkey handled frame objects with certain names. An attacker could use this flaw to cause a plug-in to grant its content access to another site or the local file system, violating the same-origin policy. (CVE-2011-2999)

An integer underflow flaw was found in the way SeaMonkey handled large JavaScript regular expressions. A web page containing malicious JavaScript could cause SeaMonkey to access already freed memory, causing SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2011-2998)

All SeaMonkey users should upgrade to these updated packages, which correct these issues. After installing the update, SeaMonkey must be restarted for the changes to take effect.

Solution

Update the affected packages.
