Summary: An update for mod_nss is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 3. Description: The mod_nss module provides strong cryptography for the Apache HTTP Server via the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, using the Network Security Services (NSS) security library. The following packages have been upgraded to a newer upstream version: mod_nss (1.0.14). (BZ#1299063) Security Fix(es): * A flaw was found in the way mod_nss parsed certain OpenSSL-style cipher strings. As a result, mod_nss could potentially use ciphers that were not intended to be enabled. (CVE-2016-3099) This issue was discovered by Rob Crittenden (Red Hat). Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section. 4.
