The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-201001-05
(net-snmp: Authorization bypass)
The netsnmp_udp_fmtaddr() function (snmplib/snmpUDPDomain.c), when
using TCP wrappers for client authorization, does not properly parse
A remote, unauthenticated attacker could bypass the ACL filtering,
possibly resulting in the execution of arbitrary SNMP queries.
If possible, protect net-snmp with custom iptables rules:
iptables -s [client] -d [host] -p udp --dport 161 -j ACCEPT
iptables -s 0.0.0.0/0 -d [host] -p udp --dport 161 -j DROP

All net-snmp users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-analyzer/net-snmp-220.127.116.11-r1'
