openldap
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2020-25709, CVE-2020-25710.
More information:

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 Debian 9 stretch, these problems have been fixed in version 2.4.44+dfsg-5+deb9u6.

We recommend that you upgrade your openldap packages.
