Debian LTS Advisory DLA-2481-1 [email protected]

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

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
