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.

CVE-2014-6270 [MEDIUM] CVE-2014-6270 squid: off-by-one error in snmpHandleUdp() leading to a bss-based buffer overflow (SQUID-2014:3)
CVE-2014-6270 squid: off-by-one error in snmpHandleUdp() leading to a bss-based buffer overflow (SQUID-2014:3)
Sebastian Krahmer discovered an off-by-one error, leading to a heap-based buffer overflow flaw, in the way Squid handled UDP SNMP requests. An unauthenticated, remote attacker could possibly use this flaw to crash Squid or, potentially, execute arbitrary code.
As noted in Sebastian's original report, an SNMP port must be configured. The default configuration of Squid for Red Hat Enterprise Linux 6 and 7 does not include an snmp_port declaration (http://wiki.squid-cache.org/Features/Snmp).
