CVE-2022-24806: fedora Input Validation Flaw — Fix

Description

net-snmp provides various tools relating to the Simple Network Management Protocol. Prior to version 5.9.2, a user with read-write credentials can exploit an Improper Input Validation vulnerability when SETing malformed OIDs in master agent and subagent simultaneously. Version 5.9.2 contains a patch. Users should use strong SNMPv3 credentials and avoid sharing the credentials. Those who must use SNMPv1 or SNMPv2c should use a complex community string and enhance the protection by restricting access to a given IP address range.
