Amazon Linux AMI : nss (ALAS-2013-217)

medium Nessus Plugin ID 70221

Language:

Synopsis

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

Description

It was discovered that NSS leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2013-1620)

An out-of-bounds memory read flaw was found in the way NSS decoded certain certificates. If an application using NSS decoded a malformed certificate, it could cause the application to crash. (CVE-2013-0791)

Solution

Run 'yum update nss' to update your system.
