Mozilla Products: Multiple vulnerabilities

Background

Mozilla Firefox is an open-source web browser, Mozilla Thunderbird an open-source email client, and the Network Security Service (NSS) is a library implementing security features like SSL v.2/v.3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME and X.509 certificates. The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as ‘Mozilla Application Suite’.

Description

Multiple vulnerabilities have been discovered in Firefox, NSS, NSPR, and Thunderbird. Please review the CVE identifiers referenced below for details.

Impact

Furthermore, a remote attacker may be able to perform Man-in-the-Middle attacks, obtain sensitive information, spoof the address bar, conduct clickjacking attacks, bypass security restrictions and protection mechanisms, or have other unspecified impacts.

Workaround

There is no known workaround at this time.
