USN-2863-1: OpenSSL vulnerability

Releases

• Ubuntu 12.04

Packages

• openssl - Secure Socket Layer (SSL) cryptographic library and tools

Details

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 machine-in-the-middle attack, this flaw could
be exploited to view sensitive information.

Update instructions

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

Ubuntu 12.04

• libssl1.0.0 - 1.0.1-4ubuntu5.33

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