Debian DSA-4792-1 : openldap - security update

high Nessus Plugin ID 143002
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the openldap packages.

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