 - In OpenLDAP through 2.4.57 and 2.5.x through 2.5.1alpha, an assertion failure in slapd can occur in the issuerAndThisUpdateCheck function via a crafted packet, resulting in a denial of service (daemon exit) via a short timestamp. This is related to schema_init.c and checkTime. (CVE-2021-27212)

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