First published: Thu Jul 19 2018(Updated: )
On F5 BIG-IP 14.0.0, 13.0.0-13.1.0, 12.1.0-12.1.3, or 11.5.1-11.6.3 specifically crafted HTTP responses, when processed by a Virtual Server with an associated QoE profile that has Video enabled, may cause TMM to incorrectly buffer response data causing the TMM to restart resulting in a Denial of Service.
