Amazon Linux AMI : mod_nss (ALAS-2013-253)

medium Nessus Plugin ID 72266

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A flaw was found in the way mod_nss handled the NSSVerifyClient setting for the per-directory context. When configured to not require a client certificate for the initial connection and only require it for a specific directory, mod_nss failed to enforce this requirement and allowed a client to access the directory when no valid client certificate was provided. (CVE-2013-4566)

Solution

Run 'yum update mod_nss' to update your system.
