CVE-2018-1089
389-ds-base before versions 1.4.0.9, 1.3.8.1, 1.3.6.15 did not properly handle long search filters with characters needing escapes, possibly leading to buffer overflows.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
389-ds-base before versions 1.4.0.9, 1.3.8.1, 1.3.6.15 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.
