high Nessus Plugin ID 158937

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5328-2 advisory.

 USN-5328-1 fixed a vulnerability in OpenSSL. This update provides the corresponding update for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM.

 Original advisory details:

 Tavis Ormandy discovered that OpenSSL incorrectly parsed certain

 certificates. A remote attacker could possibly use this issue to cause

 OpenSSH to stop responding, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libssl-dev, libssl1.0.0 and / or openssl packages.
