Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Matthew Vernon discovered that OpenSSH did not correctly check SSHFP
DNS records if a server presented an unacceptable host certificate. A
malicious server could use this issue to disable SSHFP checking.

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 openssh-client package.
