K30201296: SOCKS proxy vulnerability CVE-2017-0303

Security Advisory

Original Publication Date: Oct 27, 2017
Updated Date: Dec 22, 2017

Security Advisory Description

Under limited circumstances, connections handled by a virtual server with an
associated SOCKS profile may not be properly cleaned up, potentially leading to
resource starvation. (CVE-2017-0303)

Impact

Connections may remain in the connection table that you can only remove by
restarting the Traffic Management Microkernel (TMM). Over time, the BIG-IP
system may be unable to process further connections.

Security Advisory Status

F5 Product Development has assigned ID 641360 (BIG-IP) to this vulnerability.
