The AgentX subagent in Net-SNMP before 5.4.4 allows remote attackers to cause a denial of service (hang) by sending a multi-object request with an Object ID (OID) containing more subids than previous requests, a different vulnerability than CVE-2012-6151.

Net-SNMP 5.7.1 and earlier, when AgentX is registering to handle a MIB and processing GETNEXT requests, allows remote attackers to cause a denial of service (crash or infinite loop, CPU consumption, and hang) by causing the AgentX subagent to timeout.

Integer overflow in the AgentX::receive_agentx function in AgentX++ 1.4.16, as used in RealNetworks Helix Server and Helix Mobile Server 11.x through 13.x and other products, allows remote attackers to execute arbitrary code via a request with a crafted payload length.

Stack-based buffer overflow in the AgentX::receive_agentx function in AgentX++ 1.4.16, as used in RealNetworks Helix Server and Helix Mobile Server 11.x through 13.x and other products, allows remote attackers to execute arbitrary code via unspecified vectors.

snmp_api.c in snmpd in Net-SNMP 5.2.x before 5.2.2, 5.1.x before 5.1.3, and 5.0.x before 5.0.10.2, when running in master agentx mode, allows remote attackers to cause a denial of service (crash) by causing a particular TCP disconnect, which triggers a free of an incorrect variable, a different vulnerability than CVE-2005-2177.

Multiple buffer overflows in Ethereal 0.10.12 and earlier might allow remote attackers to execute arbitrary code via unknown vectors in the (1) SLIMP3 and (2) AgentX dissector.

Unknown vulnerability in the (1) AgentX dissector, (2) PER dissector, (3) DOCSIS dissector, (4) SCTP graphs, (5) HTTP dissector, (6) DCERPC, (7) DHCP, (8) RADIUS dissector, (9) Telnet dissector, (10) IS-IS LSP dissector, or (11) NCP dissector in Ethereal 0.8.19 through 0.10.11 allows remote attackers to cause a denial of service (application crash or abort) via unknown attack vectors.
