RHEL 4 / 5 : firefox (RHSA-2010:0782)

Synopsis

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

Description

The remote Redhat Enterprise Linux 4 / 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0782 advisory.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox. Network Security Services (NSS) is a set of libraries designed to support the development of security-enabled client and server applications.

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-2010-3175, CVE-2010-3176, CVE-2010-3179, CVE-2010-3183, CVE-2010-3180)

A flaw was found in the way the Gopher parser in Firefox converted text into HTML. A malformed file name on a Gopher server could, when accessed by a victim running Firefox, allow arbitrary JavaScript to be executed in the context of the Gopher domain. (CVE-2010-3177)

A same-origin policy bypass flaw was found in Firefox. An attacker could create a malicious web page that, when viewed by a victim, could steal private data from a different website the victim has loaded with Firefox.
(CVE-2010-3178)

A flaw was found in the script that launches Firefox. The LD_LIBRARY_PATH variable was appending a . character, which could allow a local attacker to execute arbitrary code with the privileges of a different user running Firefox, if that user ran Firefox from within an attacker-controlled directory. (CVE-2010-3182)

This update also provides NSS version 3.12.8 which is required by the updated Firefox version, fixing the following security issues:

It was found that the SSL DHE (Diffie-Hellman Ephemeral) mode implementation for key exchanges in Firefox accepted DHE keys that were 256 bits in length. This update removes support for 256 bit DHE keys, as such keys are easily broken using modern hardware. (CVE-2010-3173)

A flaw was found in the way NSS matched SSL certificates when the certificates had a Common Name containing a wildcard and a partial IP address. NSS incorrectly accepted connections to IP addresses that fell within the SSL certificate's wildcard range as valid SSL connections, possibly allowing an attacker to conduct a man-in-the-middle attack.
(CVE-2010-3170)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.6.11. You can find a link to the Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.6.11, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL firefox package based on the guidance in RHSA-2010:0782.
