Debian DSA-3033-1 : nss - security update

High Nessus Plugin ID 77880

Synopsis

The remote Debian host is missing a security-related update.

Description

Antoine Delignat-Lavaud from Inria discovered an issue in the way NSS (the Mozilla Network Security Service library) was parsing ASN.1 data used in signatures, making it vulnerable to a signature forgery attack.

An attacker could craft ASN.1 data to forge RSA certificates with a valid certification chain to a trusted CA.

Solution

Upgrade the nss packages.

For the stable distribution (wheezy), this problem has been fixed in version 2:3.14.5-1+deb7u2.
