Debian Security Advisory DSA-4792-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
November 17, 2020 https://www.debian.org/security/faq
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
Further information about Debian Security Advisories, how to apply
these updates to your system and frequently asked questions can be
