Name of the Vulnerable Software and Affected Versions F5 BIG-IP versions 13.1.0 through 13.1.0.3

Description The issue occurs when ASM and AVR are both provisioned and the virtual server is configured with a DNS profile, where the Protocol setting is set to TCP. This can cause TMM to restart while processing DNS requests.

Recommendations For F5 BIG-IP versions 13.1.0 through 13.1.0.3, consider reconfiguring the virtual server to use a different protocol setting until a fix is available. As a temporary workaround, restrict the use of the DNS profile with TCP protocol to minimize the risk of TMM restarts.
