openssl update
==========================
==========================
========================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

OpenSSL TLSv1.2 support has been improved.

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

Details:

For compatibility reasons, OpenSSL in Ubuntu 12.04 LTS disables TLSv1.2
by default when being used as a client. When forcing the use of TLSv1.2,
another compatibility feature (OPENSSL_MAX_TLS1_2_CIPHER_LENGTH) was used=

that would truncate the cipher list. This would prevent certain ciphers
from being selected, and would prevent secure renegotiations. This update=

removes the cipher list truncation workaround when forcing the use of
TLSv1.2.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
libssl1.0.0 1.0.1-4ubuntu5.18

After a standard system update you need to reboot your computer to make
all the necessary changes.
