Debian Security Advisory DSA-4860-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
February 20, 2021 https://www.debian.org/security/faq
Package : openldap
CVE ID : CVE-2021-27212
A vulnerability in the Certificate List Exact Assertion validation was
discovered in OpenLDAP, a free implementation of the Lightweight
Directory Access Protocol. An unauthenticated remote attacker can take
advantage of this flaw to cause a denial of service (slapd daemon crash)
via specially crafted packets.
For the stable distribution (buster), this problem has been fixed in
version 2.4.47+dfsg-3+deb10u6.
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
