Debian DLA-2199-1 : openldap security update

high Nessus Plugin ID 136289

Language:

Synopsis

The remote Debian host is missing a security update.

Description

A vulnerability was discovered in OpenLDAP, a free implementation of the Lightweight Directory Access Protocol. LDAP search filters with nested boolean expressions can result in denial of service (slapd daemon crash).

For Debian 8 'Jessie', this problem has been fixed in version 2.4.40+dfsg-1+deb8u6.

We recommend that you upgrade your openldap packages.

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.
