{"id":"UBUNTU-CVE-2018-1089","details":"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.","modified":"2025-09-08T16:44:37Z","published":"2018-05-09T15:29:00Z","upstream":["CVE-2018-1089"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2018-1089"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2018/05/07/2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2018-1089"}],"affected":[{"package":{"name":"389-ds-base","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/389-ds-base@1.3.4.9-1ubuntu0.1~esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.3.12-1build1","1.3.3.13-1","1.3.4.5-2","1.3.4.8-1","1.3.4.8-3","1.3.4.8-3ubuntu1","1.3.4.8-4","1.3.4.9-1","1.3.4.9-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"389-ds","binary_version":"1.3.4.9-1ubuntu0.1~esm1"},{"binary_name":"389-ds-base","binary_version":"1.3.4.9-1ubuntu0.1~esm1"},{"binary_name":"389-ds-base-dev","binary_version":"1.3.4.9-1ubuntu0.1~esm1"},{"binary_name":"389-ds-base-libs","binary_version":"1.3.4.9-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-1089.json"}},{"package":{"name":"389-ds-base","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/389-ds-base@1.3.7.10-1ubuntu1+esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.7.5-1","1.3.7.5-1build1","1.3.7.5-1build2","1.3.7.9-1","1.3.7.10-1","1.3.7.10-1ubuntu1","1.3.7.10-1ubuntu1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"389-ds","binary_version":"1.3.7.10-1ubuntu1+esm1"},{"binary_name":"389-ds-base","binary_version":"1.3.7.10-1ubuntu1+esm1"},{"binary_name":"389-ds-base-dev","binary_version":"1.3.7.10-1ubuntu1+esm1"},{"binary_name":"389-ds-base-libs","binary_version":"1.3.7.10-1ubuntu1+esm1"},{"binary_name":"python3-dirsrvtests","binary_version":"1.3.7.10-1ubuntu1+esm1"},{"binary_name":"python3-lib389","binary_version":"1.3.7.10-1ubuntu1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2018/UBUNTU-CVE-2018-1089.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
