{"id":"UBUNTU-CVE-2019-14833","details":"A flaw was found in Samba, all versions starting samba 4.5.0 before samba 4.9.15, samba 4.10.10, samba 4.11.2, in the way it handles a user password change or a new password for a samba user. The Samba Active Directory Domain Controller can be configured to use a custom script to check for password complexity. This configuration can fail to verify password complexity when non-ASCII characters are used in the password, which could lead to weak passwords being set for samba users, making it vulnerable to dictionary attacks.","modified":"2026-04-22T13:33:34.037792Z","published":"2019-10-29T00:00:00Z","related":["USN-4167-1"],"upstream":["CVE-2019-14833"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-14833"},{"type":"REPORT","url":"https://www.samba.org/samba/security/CVE-2019-14833.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4167-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-14833"}],"affected":[{"package":{"name":"samba","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/samba@2:4.7.6+dfsg~ubuntu-0ubuntu2.13?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13"}]}],"versions":["2:4.6.7+dfsg-1ubuntu3","2:4.7.1+dfsg-1ubuntu1","2:4.7.3+dfsg-1ubuntu1","2:4.7.4+dfsg-1ubuntu1","2:4.7.6+dfsg~ubuntu-0ubuntu1","2:4.7.6+dfsg~ubuntu-0ubuntu2","2:4.7.6+dfsg~ubuntu-0ubuntu2.2","2:4.7.6+dfsg~ubuntu-0ubuntu2.4","2:4.7.6+dfsg~ubuntu-0ubuntu2.5","2:4.7.6+dfsg~ubuntu-0ubuntu2.6","2:4.7.6+dfsg~ubuntu-0ubuntu2.7","2:4.7.6+dfsg~ubuntu-0ubuntu2.9","2:4.7.6+dfsg~ubuntu-0ubuntu2.10","2:4.7.6+dfsg~ubuntu-0ubuntu2.11"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"ctdb"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"libnss-winbind"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"libpam-winbind"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"libparse-pidl-perl"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"libsmbclient"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"libwbclient0"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"python-samba"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"registry-tools"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"samba"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"samba-common"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"samba-common-bin"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"samba-dsdb-modules"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"samba-libs"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"samba-testsuite"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"samba-vfs-modules"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"smbclient"},{"binary_version":"2:4.7.6+dfsg~ubuntu-0ubuntu2.13","binary_name":"winbind"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-14833.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
