F5 will not develop a fix for vulnerable products that do not already have a fixed version listed in this article, and will not update this table with subsequent vulnerable releases in the associated branches. F5 recommends that you update to more recent, non-vulnerable versions whenever feasible. For more information, refer to K4602: Overview of the F5 security vulnerability response policy.
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 Fixes introduced in 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.
To mitigate this vulnerability, you can restart the snmpd process when memory consumption is high. To do so, perform the following procedure:
Impact of action: SNMP functionality is disrupted while the snmpd process restarts.
restart /sys service snmpd
show /sys service snmpd
Output appears similar to the following example:
snmpd run (pid 22143) 8 seconds, 1 start
