Simple Network Management Protocol (SNMP) is the lifeblood of many networks
and is present on virtually every type of device. This protocol allows devices (routers,
switches, servers, and so on) to be managed across many enterprises and the Internet.
Unfortunately, SNMP isn’t the most secure protocol. Even worse, several buffer overflow
conditions were found in SNMP that affect dozens of vendors and hundreds of different
platforms. Much of the research related to this vulnerability was discovered by the Protos
Project and their corresponding Protos test suite. The Protos Project focused on identifying weaknesses in
the SNMPv1 protocol associated with trap (messages sent from agents to managers) and
request (messages sent from managers to agents) handling. These vulnerabilities range
from causing a denial of service (DoS) condition to allowing an attacker to execute commands remotely
