Ubuntu 16.04 LTS : OpenStack Neutron vulnerability (USN-4036-1)

medium Nessus Plugin ID 126256

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4036-1 advisory.

 Erik Olof Gunnar Andersson discovered that OpenStack Neutron incorrectly handled certain security group rules in the iptables firewall module. An authenticated attacker could possibly use this issue to block further application of security group rules for other instances.

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 packages.
