libNSS Hello Challenge Remote Heap Overflow



The remote host is vulnerable to a buffer overflow.


The remote host is running a vulnerable version of the Mozilla web browser. This version is based on a vulnerable version of libNSS, the Network Security Service library that implements the SSL/TLS protocol. It is reported that versions of libNSS up to 3.9.0 are prone to a remote heap overflow in the processing of the 'hello' message. An attacker may use this overflow to execute arbitrary code on the remote host.


Upgrade or patch according to vendor recommendations.
