Debian DSA-3868-1 : openldap - security update

medium Nessus Plugin ID 100522
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.


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


Karsten Heymann discovered that the OpenLDAP directory server can be crashed by performing a paged search with a page size of 0, resulting in denial of service. This vulnerability is limited to the MDB storage backend.


Upgrade the openldap packages.

For the stable distribution (jessie), this problem has been fixed in version 2.4.40+dfsg-1+deb8u3.
