Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of openldap installed on the remote host is prior to 2.4.44-23. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1638 advisory.

 - A NULL pointer dereference was found in OpenLDAP server and was fixed in openldap 2.4.55, during a request for renaming RDNs. An unauthenticated attacker could remotely crash the slapd process by sending a specially crafted request, causing a Denial of Service. (CVE-2020-25692)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
