{"id":"UBUNTU-CVE-2019-3461","details":"Debian tmpreaper version 1.6.13+nmu1 has a race condition when doing a (bind) mount via rename() which could result in local privilege escalation. Mounting via rename() could potentially lead to a file being placed elsewhereon the filesystem hierarchy (e.g. /etc/cron.d/) if the directory being cleaned up was on the same physical filesystem. Fixed versions include 1.6.13+nmu1+deb9u1 and 1.6.14.","modified":"2026-02-04T03:30:23.889343Z","published":"2019-02-04T00:00:00Z","related":["USN-4077-1"],"upstream":["CVE-2019-3461"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-3461"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4077-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-3461"}],"affected":[{"package":{"name":"tmpreaper","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/tmpreaper@1.6.13+nmu1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.13+nmu1"],"ecosystem_specific":{"binaries":[{"binary_name":"tmpreaper","binary_version":"1.6.13+nmu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-3461.json"}},{"package":{"name":"tmpreaper","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/tmpreaper@1.6.13+nmu1+deb9u1build0.16.04.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6.13+nmu1+deb9u1build0.16.04.1"}]}],"versions":["1.6.13+nmu1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"tmpreaper","binary_version":"1.6.13+nmu1+deb9u1build0.16.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-3461.json"}},{"package":{"name":"tmpreaper","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/tmpreaper@1.6.13+nmu1+deb9u1build0.18.04.1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6.13+nmu1+deb9u1build0.18.04.1"}]}],"versions":["1.6.13+nmu1","1.6.13+nmu1build1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"tmpreaper","binary_version":"1.6.13+nmu1+deb9u1build0.18.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-3461.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
