{"id":"UBUNTU-CVE-2026-35362","details":"The safe_traversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use (TOCTOU) symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize these protections, leaving directory traversal operations vulnerable to symlink race conditions.","modified":"2026-05-14T12:22:03.684648323Z","published":"2026-04-22T17:16:00Z","upstream":["CVE-2026-35362"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-35362"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-35362"},{"type":"REPORT","url":"https://github.com/uutils/coreutils/pull/9792"}],"affected":[{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rust-coreutils?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.20-1","0.0.22-1","0.0.23-1","0.0.23-2","0.0.23-3","0.0.24-1","0.0.24-2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0.24-2","binary_name":"rust-coreutils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35362.json"}},{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rust-coreutils?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.30-1","0.0.30-2","0.0.30-2ubuntu2","0.1.0-0ubuntu1","0.1.0+git20250711.2ba3a33-0ubuntu1","0.1.0+git20250711.2ba3a33-0ubuntu2","0.1.0+git20250711.2ba3a33-0ubuntu3","0.1.0+git20250711.2ba3a33-0ubuntu4","0.1.0+git20250801.cf79675-0ubuntu1","0.1.0+git20250813.4af2a84-0ubuntu2","0.1.0+git20250813.4af2a84-0ubuntu4","0.1.0+git20250813.4af2a84-0ubuntu6","0.1.0+git20250813.4af2a84-0ubuntu7","0.2.2-0ubuntu1","0.2.2-0ubuntu2","0.2.2-0ubuntu2.1"],"ecosystem_specific":{"binaries":[{"binary_name":"rust-coreutils","binary_version":"0.2.2-0ubuntu2.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35362.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
