Package        : openldap
CVE ID         : CVE-2020-25709 CVE-2020-25710

Two vulnerabilities in the certificate list syntax verification and
in the handling of CSN normalization were discovered in OpenLDAP, a
free implementation of the Lightweight Directory Access Protocol.
An unauthenticated remote attacker can take advantage of these
flaws to cause a denial of service (slapd daemon crash) via
specially crafted packets.

For the stable distribution (buster), these problems have been fixed in
version 2.4.47+dfsg-3+deb10u4.

We recommend that you upgrade your openldap packages.

For the detailed security status of openldap please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/openldap
