{"id":"DEBIAN-CVE-2018-5709","details":"An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable \"dbentry-\u003en_key_data\" in kadmin/dbutil/dump.c that can store 16-bit data but unknowingly the developer has assigned a \"u4\" variable to it, which is for 32-bit data. An attacker can use this vulnerability to affect other artifacts of the database as we know that a Kerberos database dump file contains trusted data.","modified":"2026-09-01T20:02:43.886838877Z","published":"2018-01-16T09:29:00.500Z","upstream":["CVE-2018-5709"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-5709"}],"affected":[{"package":{"name":"krb5","ecosystem":"Debian:12","purl":"pkg:deb/debian/krb5?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.20.1-2","1.20.1-2+deb12u1","1.20.1-2+deb12u2","1.20.1-2+deb12u3","1.20.1-2+deb12u4","1.20.1-2+deb12u5","1.20.1-2+loong64","1.20.1-3","1.20.1-4","1.20.1-5","1.20.1-5.1","1.20.1-5.1~exp1","1.20.1-6","1.21.2-1","1.21.3-1","1.21.3-2","1.21.3-3","1.21.3-4","1.21.3-5","1.22.1-1","1.22.1-2","1.22.1-2.1","1.22.1-3"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-5709.json"}},{"package":{"name":"krb5","ecosystem":"Debian:13","purl":"pkg:deb/debian/krb5?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.21.3-5","1.21.3-5+deb13u1","1.22.1-1","1.22.1-2","1.22.1-2.1","1.22.1-3"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-5709.json"}},{"package":{"name":"krb5","ecosystem":"Debian:14","purl":"pkg:deb/debian/krb5?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.21.3-5","1.22.1-1","1.22.1-2","1.22.1-2.1","1.22.1-3"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-5709.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
