CVE-2013-4449

CVSS v2.0

4.3

Medium

VectorAV:N/AC:M/Au:N/C:N/I:N/A:P
Name of the Vulnerable Software and Affected Versions OpenLDAP versions 2.4.23 and earlier
Description The issue is related to a denial of service (slapd crash) that can be caused by remote attackers. This can happen when the rwm overlay in OpenLDAP does not properly count references, allowing attackers to unbind immediately after a search request. The exploitation can be done remotely and may lead to a disruption in the availability of protected information.
Recommendations For OpenLDAP version 2.4.23, consider updating to a newer version to resolve the issue. For versions prior to 2.4.23, update to version 2.4.23 or later to mitigate the risk. As a temporary workaround, consider restricting access to the rwm overlay until a patch is available.
