{"id":"DEBIAN-CVE-2025-14905","details":"A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the `schema_attr_enum_callback` function within the `schema.c` file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting characters. When a large number of aliases are processed, this oversight can lead to a heap overflow, potentially allowing a remote attacker to cause a Denial of Service (DoS) or achieve Remote Code Execution (RCE).","modified":"2026-09-01T20:04:52.455399185Z","published":"2026-02-23T16:29:35.620Z","upstream":["CVE-2025-14905"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-14905"}],"affected":[{"package":{"name":"389-ds-base","ecosystem":"Debian:12","purl":"pkg:deb/debian/389-ds-base?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.1+dfsg1-1","2.3.1+dfsg1-1+deb12u1","2.3.4+dfsg1-1","2.3.4+dfsg1-1.1","2.4.4+dfsg1-1","2.4.4+dfsg1-3","2.4.5+dfsg1-1","3.0.2+dfsg1-1","3.1.1+dfsg1-1","3.1.1+dfsg1-2","3.1.1+dfsg1-3","3.1.2+dfsg1-1","3.1.2+vendor1-1","3.1.2+vendor1-2","3.3.0-1","3.3.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-14905.json"}},{"package":{"name":"389-ds-base","ecosystem":"Debian:13","purl":"pkg:deb/debian/389-ds-base?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.2+dfsg1-1+deb13u1"}]}],"versions":["3.1.2+dfsg1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-14905.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H"}]}
