Name of the Vulnerable Software and Affected Versions Net-SNMP versions prior to 5.8

Description The issue is related to a NULL Pointer Exception bug in the snmp oid compare function. This bug can be exploited by an unauthenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.
