Doc Text:
It was found that 389-ds-base did not properly handle long search filters with characters needing escapes, possibly leading to buffer overflows. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.

Description Adam Mariš 2018-03-23 06:05:11 EDT
It is possible to crash ns-slapd (and ipa-dnskeysyncd afterwards) with crafted ldapsearch query with very long filter value both as anonymous or authenticated user. The crash can be similarly triggered with a query via the FreeIPA API as an authenticated user.
