Name of the Vulnerable Software and Affected Versions OpenLDAP versions 2.4.44 and earlier

Description The issue allows a user with access to search the directory to crash slapd by issuing a search including the Paged Results control with a page size of 0. This is due to a double free vulnerability in the servers/slapd/back-mdb/search.c file.

Recommendations For OpenLDAP versions 2.4.44 and earlier, consider restricting access to the search function with the Paged Results control until a fix is available. As a temporary workaround, avoid using a page size of 0 in searches to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
