Tail-f, a Cisco company, has released software updates that address the vulnerabilities described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have a current license and have a valid support and maintenance agreement. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of their license agreement with Tail-f Systems AB. Security software updates do not entitle customers to a new software license or additional software feature sets.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution.
Customers who have a current license and have a valid support and maintenance agreement can download the fixed version of software from their existing Tail-f delivery server download account.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to open a support ticket in the Tail-f Support system.
