medium Nessus Plugin ID 87815

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libssl1.0.0 package.
