Debian DSA-4845-1 : openldap - security update

high Nessus Plugin ID 146122

Synopsis

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

Description

Several vulnerabilities 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, infinite loops) 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+deb10u5.
