Amazon Linux AMI : openldap (ALAS-2014-294)

medium Nessus Plugin ID 72750

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The rwm overlay in OpenLDAP 2.4.23, 2.4.36, and earlier does not properly count references, which allows remote attackers to cause a denial of service (slapd crash) by unbinding immediately after a search request, which triggers rwm_conn_destroy to free the session context while it is being used by rwm_op_search.

Solution

Run 'yum update openldap' to update your system.
