Description
On versions 15.1.0-15.1.0.5, 14.1.0-14.1.2.3, 13.1.0-13.1.3.4, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1, when a BIG-IP system that has a virtual server configured with an HTTP compression profile processes compressed HTTP message payloads that require deflation, a Slowloris-style attack can trigger an out-of-memory condition on the BIG-IP system.
