Several vulnerabilities have been discovered in NET SNMP, a suite of Simple Network Management Protocol applications. The Common Vulnerabilities and Exposures project identifies the following problems: Wes Hardaker reported that the SNMPv3 HMAC verification relies on the client to specify the HMAC length, which allows spoofing of authenticated SNMPv3 packets. John Kortink reported a buffer overflow in the __snprint_value function in snmp_get causing a denial of service and potentially allowing the execution of arbitrary code via a large OCTETSTRING in an attribute value pair (AVP). It was reported that an integer overflow in the netsnmp_create_subtree_cache function in agent/snmp_agent.c allows remote attackers to cause a denial of service attack via a crafted SNMP GETBULK request.
