Description Arvid Requate univentionstaff 2017-06-01 18:02:39 CEST
Attached is a patch for ITS 8655:

* servers/slapd/back-mdb/search.c in OpenLDAP through 2.4.44 is prone to a double free vulnerability. A user with access to search the directory can crash slapd by issuing a search including the Paged Results control with a page size of 0. (CVE-2017-9287)
