Problema de seguridad: SNMP 'GETBULK' reflexin DDOS - Think Server RS160. The following can be used as a proof of concept for amplification. Integer overflow in the netsnmp_create_subtree_cache function in agent/snmp_agent.c in net-snmp 5.4 before 5.4.2.1, 5.3 before 5.3.2.3, and 5.2 before 5.2.5.1 allows remote attackers to cause a denial of service (crash) via a crafted SNMP GETBULK request, which triggers a heap-based buffer overflow, related to the number of responses or repeats. Depending on the MIBs in use, the response can be 6x the size of the request, and because SNMP utilizes UDP, this can be used to conduct traffic amplification attacks against other assets, typically in the form of distributed reflected denial of service (DRDoS) attacks. The SNMP manager will send this type of message to find out what information is available from the device.
