{"id":"UBUNTU-CVE-2019-14287","details":"In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a \"sudo -u \\#$((0xffffffff))\" command.","modified":"2026-02-04T02:27:35.234444Z","published":"2019-10-14T15:00:00Z","related":["USN-4154-1"],"upstream":["CVE-2019-14287"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-14287"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4154-1"},{"type":"REPORT","url":"https://www.sudo.ws/alerts/minus_1_uid.html"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-14287"}],"affected":[{"package":{"name":"sudo","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/sudo@1.8.9p5-1ubuntu1.5+esm2?arch=source&distro=trusty/esm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.8.9p5-1ubuntu1.5+esm2"}]}],"versions":["1.8.6p3-0ubuntu3","1.8.8-2ubuntu1","1.8.8-2ubuntu2","1.8.9p4-1ubuntu1","1.8.9p4-1ubuntu2","1.8.9p5-1ubuntu1","1.8.9p5-1ubuntu1.1","1.8.9p5-1ubuntu1.2","1.8.9p5-1ubuntu1.3","1.8.9p5-1ubuntu1.4","1.8.9p5-1ubuntu1.5+esm1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro","binaries":[{"binary_version":"1.8.9p5-1ubuntu1.5+esm2","binary_name":"sudo"},{"binary_version":"1.8.9p5-1ubuntu1.5+esm2","binary_name":"sudo-ldap"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-14287.json"}},{"package":{"name":"sudo","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/sudo@1.8.16-0ubuntu1.8?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.8.16-0ubuntu1.8"}]}],"versions":["1.8.12-1ubuntu3","1.8.16-0ubuntu1","1.8.16-0ubuntu1.1","1.8.16-0ubuntu1.2","1.8.16-0ubuntu1.3","1.8.16-0ubuntu1.4","1.8.16-0ubuntu1.5","1.8.16-0ubuntu1.6","1.8.16-0ubuntu1.7"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"1.8.16-0ubuntu1.8","binary_name":"sudo"},{"binary_version":"1.8.16-0ubuntu1.8","binary_name":"sudo-ldap"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-14287.json"}},{"package":{"name":"sudo","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/sudo@1.8.21p2-3ubuntu1.1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.8.21p2-3ubuntu1.1"}]}],"versions":["1.8.20p2-1ubuntu1","1.8.21p2-2ubuntu1","1.8.21p2-3ubuntu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_version":"1.8.21p2-3ubuntu1.1","binary_name":"sudo"},{"binary_version":"1.8.21p2-3ubuntu1.1","binary_name":"sudo-ldap"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-14287.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
