Security Advisory
Original Publication Date: Apr 19, 2017
Updated Date: Nov 02, 2018
Security Advisory Description
The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel

Security Advisory Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.
Mitigation
To mitigate this vulnerability, you should permit management access to F5
products only over a secure network and restrict command line access for
affected systems to trusted users. For more information, refer to K13309:
Restricting access to the Configuration utility by source IP address (11.x -
14.x) and K13092: Overview of securing access to the BIG-IP system.
Impact of action: Performing the suggested mitigation should not have a
negative impact on your system.
