F5 Networks BIG-IP : SOCKS proxy vulnerability (K30201296)

Medium Nessus Plugin ID 104192


The remote device is missing a vendor-supplied security patch.


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)


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


Upgrade to one of the non-vulnerable versions listed in the F5 Solution K30201296.
