Description

A flaw was found in the way NSS parsed ASN.1 (Abstract Syntax Notation One) input from certain RSA signatures. A remote attacker could use this flaw to forge RSA certificates by providing a specially crafted signature to an application using NSS. (CVE-2014-1568)

After installing this update, applications using NSS must be restarted for this update to take effect.
