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-2013-0801, CVE-2013-1674, CVE-2013-1675, CVE-2013-1676, CVE-2013-1677, CVE-2013-1678, CVE-2013-1679, CVE-2013-1680 and CVE-2013-1681 to these issues.

A flaw was found in the way Firefox handled Content Level Constructors. A malicious site could use this flaw to perform cross-site scripting (XSS) attacks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-1670 to this issue.

More information about these vulnerabilities can be found in the security advisory issued by Red Hat:

Recommended Actions for System Products:
Avaya strongly recommends following the 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 products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but the System Product operating system or application should not be modified unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

Mitigating Factors:

When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:

Vulnerability Mitigating Factors
CVE-2013-0801
CVE-2013-1670
CVE-2013-1674
CVE-2013-1675
CVE-2013-1676
CVE-2013-1677
CVE-2013-1678
CVE-2013-1679
CVE-2013-1680
CVE-2013-1681
These are a Low risk for one-X Client Enablement Services because exploitation would require Internet browsing, which is considered non-standard user interaction.
There is no risk for all other products as only xulrunner is installed.

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.

In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
