Calendar Grey May 12, 2015
Dist Ubuntu Esm H88
Support for TLSv1.2 clients has been restored in Ubuntu 12.04 LTS following this OpenSSL upgrade to address compatibility challenges.
OpenSSL TLSv1.2 client support has been enabled in Ubuntu 12.04 LTS.

Summary

OpenSSL TLSv1.2 client support has been enabled in Ubuntu 12.04 LTS.

Software Description:

- openssl: Secure Socket Layer (SSL) cryptographic library and tools

Details:

For compatibility reasons, Ubuntu 12.04 LTS shipped OpenSSL with TLSv1.2

disabled when being used as a client.

This update re-enables TLSv1.2 by default now that the majority of

problematic sites have been updated to fix compatibility issues.

For problematic environments, TLSv1.2 can be disabled again by setting the

OPENSSL_NO_CLIENT_TLS1_2 environment variable before library

initialization.
