Security Advisory
Original Publication Date: May 05, 2017
Updated Date: May 05, 2017
Applies to (see versions):
Security Advisory Description
Specific websocket traffic patterns may cause a disruption of service for
virtual servers configured to use the websocket profile. (CVE-2016-9253)
Note: Virtual servers configured to use the HTTP profile (and no websocket
profile) that process websocket traffic are not vulnerable to this issue. This
issue only affects the BIG-IP data plane; there is no control plane exposure
to this vulnerability.
Impact
An attacker may be able to disrupt service on the BIG-IP system by sending
crafted websocket traffic to the virtual server.
Security Advisory Status
F5 Product Development has assigned ID 630150 (BIG-IP) to this vulnerability.
