This script is Copyright (C) 2006-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200611-25
(OpenLDAP: Denial of Service vulnerability)

Evgeny Legerov has discovered that the truncation of an incoming
authcid longer than 255 characters and ending with a space as the 255th
character will lead to an improperly computed name length. This will
trigger an assert in the libldap code.

Impact :

By sending a BIND request with a specially crafted authcid parameter to
an OpenLDAP service, a remote attacker can cause the service to crash.

Workaround :

There is no known workaround at this time.

Solution :

All OpenLDAP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose 'net-nds/openldap'

Risk factor :

Medium / CVSS Base Score : 5.0
