Gentoo Linux Security Advisory 201001-5 – A remote attacker can bypass the tcp-wrappers client authorization in net-snmp. The netsnmp_udp_fmtaddr() function (snmplib/snmpUDPDomain.c), when using TCP wrappers for client authorization, does not properly parse hosts.allow rules. Versions less than 5.4.2.1-r1 are affected.
