1. Overview:

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

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-2012-1948, CVE-2012-1951, CVE-2012-1952, CVE-2012-1953, CVE-2012-1954, CVE-2012-1958, CVE-2012-1962, and CVE-2012-1967 to these issues.

A malicious web page could bypass same-compartment security wrappers (SCSW) and execute arbitrary code with chrome privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1959 to this issue.

A flaw in the context menu functionality in Firefox could allow a malicious website to bypass intended restrictions and allow a cross-site scripting attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1966 to this issue.

A page different to that in the address bar could be displayed when dragging and dropping to the address bar, possibly making it easier for a malicious site or user to perform a phishing attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1950 to this issue.

A flaw in the way Firefox called history.forward and history.back could allow an attacker to conceal a malicious URL, possibly tricking a user into believing they are viewing a trusted site. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1955to this issue.

A flaw in a parser utility class used by Firefox to parse feeds (such as RSS) could allow an attacker to execute arbitrary JavaScript with the privileges of the user running Firefox. This issue could have affected other browser components or add-ons that assume the class returns sanitized input. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1957 to this issue.

A flaw in the way Firefox handled X-Frame-Options headers could allow a malicious website to perform a clickjacking attack.The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1961 to this issue.

A flaw in the way Content Security Policy (CSP) reports were generated by Firefox could allow a malicious web page to steal a victim's OAuth 2.0 access tokens and OpenID credentials. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1963 to this issue.

A flaw in the way Firefox handled certificate warnings could allow a man-in-the-middle attacker to create a crafted warning, possibly tricking a user into accepting an arbitrary certificate as trusted. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1964 to this issue.

A flaw in the way Firefox handled feed:javascript URLs could allow output filtering to be bypassed, possibly leading to a cross-site scripting attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-1965 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 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 customers should not modify the System Product operating system or application 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-2012-1948
CVE-2012-1950
CVE-2012-1951
CVE-2012-1952
CVE-2012-1953
CVE-2012-1954
CVE-2012-1955
CVE-2012-1957
CVE-2012-1958
CVE-2012-1959
CVE-2012-1961
CVE-2012-1962
CVE-2012-1963
CVE-2012-1964
CVE-2012-1965
CVE-2012-1966
CVE-2012-1967
The risk is rated None for CS1000, Experience Portal, IP Office Application Server, IQ, Presence Services, Session Manager, and System Manager because only xulrunner is installed. Firefox is not installed, which would be required to exploit these vulnerabilities.
The risk is rated Low for One-X Client Enablement Services because exploitation would require Internet browsing, which is considered non-standard user interaction.

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.
