{"id":"DEBIAN-CVE-2026-35353","details":"The mkdir utility in uutils coreutils incorrectly applies permissions when using the -m flag by creating a directory with umask-derived permissions (typically 0755) before subsequently changing them to the requested mode via a separate chmod system call. In multi-user environments, this introduces a brief window where a directory intended to be private is accessible to other users, potentially leading to unauthorized data access.","modified":"2026-09-14T17:03:09.452744649Z","published":"2026-04-22T17:16:37.723Z","upstream":["CVE-2026-35353"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-35353"}],"affected":[{"package":{"name":"rust-coreutils","ecosystem":"Debian:12","purl":"pkg:deb/debian/rust-coreutils?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.17-2","0.0.17-3","0.0.17-4","0.0.17-5","0.0.17-6","0.0.19-1","0.0.19-2","0.0.19-3","0.0.20-1","0.0.21-1","0.0.22-1","0.0.23-1","0.0.23-2","0.0.23-3","0.0.24-1","0.0.24-2","0.0.26-1","0.0.26-2","0.0.26-3","0.0.26-4","0.0.26-5","0.0.27-1","0.0.27-2","0.0.27-3","0.0.30-1","0.0.30-2","0.0.30-3","0.0.30-3~exp1","0.0.30-4","0.10.0-1","0.11.0-1","0.11.0-2","0.6.0-1","0.7.0-1","0.8.0-1","0.8.0-2","0.8.0-3","0.8.0-4","0.8.0-5","0.8.0-6","0.9.0-1","0.9.0-2","0.9.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-35353.json"}},{"package":{"name":"rust-coreutils","ecosystem":"Debian:13","purl":"pkg:deb/debian/rust-coreutils?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.30-2","0.0.30-3","0.0.30-3~exp1","0.0.30-4","0.10.0-1","0.11.0-1","0.11.0-2","0.6.0-1","0.7.0-1","0.8.0-1","0.8.0-2","0.8.0-3","0.8.0-4","0.8.0-5","0.8.0-6","0.9.0-1","0.9.0-2","0.9.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-35353.json"}},{"package":{"name":"rust-coreutils","ecosystem":"Debian:14","purl":"pkg:deb/debian/rust-coreutils?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.6.0-1"}]}],"versions":["0.0.30-2","0.0.30-3","0.0.30-3~exp1","0.0.30-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-35353.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
