USN-2863-1: OpenSSL vulnerability
7 January 2016
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
OpenSSL could be made to expose sensitive information over the network.
- openssl - Secure Socket Layer (SSL) cryptographic library and tools
Karthikeyan Bhargavan and Gaetan Leurent discovered that OpenSSL incorrectly allowed MD5 to be used for TLS 1.2 connections. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information.
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make all the necessary changes.
