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

high Nessus Plugin ID 80041
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
