Debian DLA-972-1 : openldap security update

medium Nessus Plugin ID 100576

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a double-free vulnerability in the 'openldap' LDAP server.

A user with access to search the directory could crash slapd by issuing a search requesting a 'Paged Results' value set to zero.

For Debian 7 'Wheezy', this issue has been fixed in openldap version 2.4.31-2+deb7u3.

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.
