Debian DLA-2544-1 : openldap security update

high Nessus Plugin ID 146191

Synopsis

The remote Debian host is missing a security 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.

For Debian 9 stretch, these problems have been fixed in version 2.4.44+dfsg-5+deb9u7.

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

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
