Debian DSA-3034-1 : iceweasel - security update

High Nessus Plugin ID 77881

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, embedded in Wheezy's Iceweasel package), 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 iceweasel packages.

For the stable distribution (wheezy), this problem has been fixed in version 24.8.1esr-1~deb7u1.
