AV:N/AC:L/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions OpenLDAP versions 2.4.13 through 2.4.40

Description The issue allows remote attackers to cause a denial of service, resulting in a crash due to a NULL pointer dereference. This can be achieved by sending a search request with an empty attribute list in a deref control.

Recommendations For OpenLDAP versions 2.4.13 through 2.4.40, consider updating to a version that contains a fix for this issue. As a temporary workaround, consider restricting access to the deref parseCtrl function in the deref.c file until a patch is available. Avoid using empty attribute lists in deref controls in search requests until the issue is resolved.
