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)
