APP: Squid snmpHandleUdp Off-by-one Buffer Overflow

This signature detects attempts to exploit a known vulnerability against Squid. A successful attack can lead to arbitrary code execution.

Extended Description

Off-by-one error in the snmpHandleUdp function in snmp_core.cc in Squid 2.x and 3.x, when an SNMP port is configured, allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted UDP SNMP request, which triggers a heap-based buffer overflow.
