NVD Description

Note: Versions mentioned in the description apply only to the upstream nss package and not the nss package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

A Null pointer dereference vulnerability exists in Mozilla Network Security Services due to a missing NULL check in PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime, which could let a remote malicious user cause a Denial of Service.
