NVD Description

Note: Versions mentioned in the description apply only to the upstream squid package and not the squid package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
