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.
