Advisory Version: 2.0
Advisory Status: Final

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-2012-1970, CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975, CVE-2012-1976, CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960, CVE-2012-3961, CVE-2012-3962, CVE-2012-3963 and CVE-2012-3964 to these issues.

A web page containing a malicious Scalable Vector Graphics (SVG) image file 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-2012-3969 and CVE-2012-3970 to these issues.

Two flaws were found in the way Firefox rendered certain images using WebGL. A web page containing malicious content could cause Firefox to crash or, under certain conditions, possibly 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-2012-3967 and CVE-2012-3968 to these issues.

A flaw was found in the way Firefox decoded embedded bitmap images in Icon Format (ICO) files. A web page containing a malicious ICO file could cause Firefox to crash or, under certain conditions, possibly execute arbitrary code with the privileges of the user running Firefox. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-3966 to this issue.

A flaw was found in the way the "eval" command was handled by the Firefox Web Console. Running "eval" in the Web Console while viewing a web page containing malicious content could possibly cause Firefox to execute arbitrary code with the privileges of the user running Firefox. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-3980 to this issue.

An out-of-bounds memory read flaw was found in the way Firefox used the format-number feature of XSLT (Extensible Stylesheet Language Transformations). A web page containing malicious content could possibly cause an information leak, or cause Firefox to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-3972 to this issue.

It was found that the SSL certificate information for a previously visited site could be displayed in the address bar while the main window displayed a new page. This could lead to phishing attacks as attackers could use this flaw to trick users into believing they are viewing a trusted site. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-3976 to this issue.

A flaw was found in the location object implementation in Firefox. Malicious content could use this flaw to possibly allow restricted content to be loaded. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-3978 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 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-2012-1970
CVE-2012-1972
CVE-2012-1973
CVE-2012-1974
CVE-2012-1975
CVE-2012-1976
CVE-2012-3956
CVE-2012-3957
CVE-2012-3958
CVE-2012-3959
CVE-2012-3960
CVE-2012-3961
CVE-2012-3962
CVE-2012-3963
CVE-2012-3964
CVE-2012-3966
CVE-2012-3967
CVE-2012-3968
CVE-2012-3969
CVE-2012-3970
CVE-2012-3972
CVE-2012-3976
CVE-2012-3978
CVE-2012-3980
These are a low risk for one-X Client Enablement Services as Firefox is installed but not configured or used by default.
There is no risk for Avaya IQ, CS1000, IP Office Application Server, Presence Services, Session Manager or System Manager as only the xulrunner component 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.

Product: Actions:
Avaya Aura® Application Enablement Services 4.x/5.x Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the AES application.
CVLAN Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the CVLAN application.
Avaya Aura® Experience Portal Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the EP application.
