Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200711-31
(Net-SNMP: Denial of Service)

The SNMP agent (snmpd) does not properly handle GETBULK requests with
an overly large 'max-repetitions' field.

Impact :

A remote unauthenticated attacker could send a specially crafted SNMP
request to the vulnerable application, possibly resulting in a high CPU
and memory consumption.

Workaround :

There is no known workaround at this time.

# emerge --sync
# emerge --ask --oneshot --verbose '>=net-analyzer/net-snmp-5.4.1-r1'
