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

This script is Copyright (C) 2013 Tenable Network Security, Inc.


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)
