Description John Helmert III gentoo-dev Security 2021-02-15 22:10:10 UTC
CVE-2021-27212:

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.


Unreleased patch: https://git.openldap.org/openldap/openldap/-/commit/9badb73425a67768c09bcaed1a9c26c684af6c30

Maintainers, please apply the patch if it looks reasonable to you.

Seems to be the same fix as the first.
