firefox security update (RHSA-2009-1674)

Original Release Date: December 22, 2009
Last Revised: July 9, 2010
Number: ASA-2009-582
Risk Level: Low
Advisory Version: 3.0
Advisory Status: Final

1. Overview:

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. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-3979, CVE-2009-3981 and CVE-2009-3986 to these issues.

A flaw was found in the Firefox NT Lan Manager (NTLM) authentication protocol implementation. If an attacker could trick a local user that has NTLM credentials into visiting a specially-crafted web page, they could send arbitrary requests, authenticated with the user's NTLM credentials, to other applications on the user's system. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3983 to this issue.

A flaw was found in the way Firefox displayed the SSL location bar indicator. An attacker could create an unencrypted web page that appears to be encrypted, possibly tricking the user into believing they are visiting a secure page. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3984 to this issue.

A flaw was found in the way Firefox displayed blank pages after a user navigates to an invalid address. If a user visits an attacker-controlled web page that results in a blank page, the attacker could inject content into that blank page, possibly tricking the user into believing they are viewing a legitimate page. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-3985 to this issue.

Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place; risk to Avaya's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update can be installed. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
