Detail

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.
