Synopsis

Description

Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.

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.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2010-3169, CVE-2010-2762)

Several use-after-free and dangling pointer flaws were found in Firefox. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2010-2760, CVE-2010-2766, CVE-2010-2767, CVE-2010-3167, CVE-2010-3168)

Multiple buffer overflow flaws were found in Firefox. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2010-2765, CVE-2010-3166)

Multiple cross-site scripting (XSS) flaws were found in Firefox. A web page containing malicious content could cause Firefox to run JavaScript code with the permissions of a different website.
(CVE-2010-2768, CVE-2010-2769)

A flaw was found in the Firefox XMLHttpRequest object. A remote site could use this flaw to gather information about servers on an internal private network. (CVE-2010-2764)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.6.9. You can find a link to the Mozilla advisories in the References section of this erratum.

Note: After installing this update, Firefox will fail to connect (with HTTPS) to a server using the SSL DHE (Diffie-Hellman Ephemeral) key exchange if the server's ephemeral key is too small. Connecting to such servers is a security risk as an ephemeral key that is too small makes the SSL connection vulnerable to attack. Refer to the Solution section for further information.

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.6.9, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected packages.
