Mandriva Linux Security Advisory : nss (MDVSA-2014:252)

high Nessus Plugin ID 80041

Language:

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

Updated nss packages fix security vulnerabilities :

In the QuickDER decoder in NSS before 3.17.3, ASN.1 DER decoding of lengths is too permissive, allowing undetected smuggling of arbitrary data (CVE-2014-1569).

This update adds support for the TLS Fallback Signaling Cipher Suite Value (TLS_FALLBACK_SCSV) in NSS, which can be used to prevent protocol downgrade attacks against applications which re-connect using a lower SSL/TLS protocol version when the initial connection indicating the highest supported protocol version fails. This can prevent a forceful downgrade of the communication to SSL 3.0, mitigating CVE-2014-3566, also known as POODLE. SSL 3.0 support has also been disabled by default in this Firefox and Thunderbird update, further mitigating POODLE.

Solution

Update the affected packages.
