July 25, 2012

openssl vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

OpenSSL incorrectly disabled TLS 1.1 and TLS 1.2 in certain applications.

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

Details:

It was discovered that OpenSSL incorrectly handled the SSL_OP_ALL setting.
This resulted in TLS 1.1 and TLS 1.2 being inadvertently disabled for
certain server and client applications.

Update instructions:

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

Ubuntu 12.04 LTS:
  libssl1.0.0                     1.0.1-4ubuntu5.3

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