Summary

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:
