Test ID:1.3.6.1.4.1.25623.1.0.68304
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0782
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2010:0782.

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.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
