Vulnerability Information

Synopsis

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

Description

Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 4, 5, and 6.

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 possibly lead to arbitrary code execution with the privileges of the user running Firefox. (CVE-2011-0080, CVE-2011-0081)

An arbitrary memory write flaw was found in the way Firefox handled out-of-memory conditions. If all memory was consumed when a user visited a malicious web page, it could possibly lead to arbitrary code execution with the privileges of the user running Firefox. (CVE-2011-0078)

An integer overflow flaw was found in the way Firefox handled the HTML frameset tag. A web page with a frameset tag containing large values for the 'rows' and 'cols' attributes could trigger this flaw, possibly leading to arbitrary code execution with the privileges of the user running Firefox. (CVE-2011-0077)

A flaw was found in the way Firefox handled the HTML iframe tag. A web page with an iframe tag containing a specially crafted source address could trigger this flaw, possibly leading to arbitrary code execution with the privileges of the user running Firefox. (CVE-2011-0075)

A flaw was found in the way Firefox displayed multiple marquee elements. A malformed HTML document could cause Firefox to execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-0074)

A flaw was found in the way Firefox handled the nsTreeSelection element. Malformed content could cause Firefox to execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-0073)

A use-after-free flaw was found in the way Firefox appended frame and iframe elements to a DOM tree when the NoScript add-on was enabled. Malicious HTML content could cause Firefox to execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-0072)

A directory traversal flaw was found in the Firefox resource:// protocol handler. Malicious content could cause Firefox to access arbitrary files accessible to the user running Firefox. (CVE-2011-0071)

A double free flaw was found in the way Firefox handled 'application/http-index-format' documents. A malformed HTTP response could cause Firefox to execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-0070)

A flaw was found in the way Firefox handled certain JavaScript cross-domain requests. If malicious content generated a large number of cross-domain JavaScript requests, it could cause Firefox to execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-0069)

A flaw was found in the way Firefox displayed the autocomplete pop-up. Malicious content could use this flaw to steal form history information. (CVE-2011-0067)

Two use-after-free flaws were found in the Firefox mObserverList and mChannel objects. Malicious content could use these flaws to execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-0066, CVE-2011-0065)

A flaw was found in the Firefox XSLT generate-id() function. This function returned the memory address of an object in memory, which could possibly be used by attackers to bypass address randomization protections. (CVE-2011-1202)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.6.17. 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 3.6.17, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected packages.

How to Run

Here is how to run the RHEL 4 / 5 / 6 : firefox (RHSA-2011:0471) as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Red Hat Local Security Checks plugin family.
On the right side table select RHEL 4 / 5 / 6 : firefox (RHSA-2011:0471) plugin ID 53580.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl redhat-RHSA-2011-0471.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a redhat-RHSA-2011-0471.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - redhat-RHSA-2011-0471.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state redhat-RHSA-2011-0471.nasl -t <IP/HOST>

Go back to menu.
