Description

As a security improvement, this update makes the following changes to the Apache package in Ubuntu 12.04 LTS :

Added support for ECC keys and ECDH ciphers.

The SSLProtocol configuration directive now allows specifying the TLSv1.1 and TLSv1.2 protocols.

Ephemeral key handling has been improved, including allowing DH parameters to be loaded from the SSL certificate file specified in SSLCertificateFile.

The export cipher suites are now disabled by default.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
