When copying with the -p (preserve) flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining original privileged bits, creating unexpected privileged executables that violate local security policies. This differs from GNU cp, which clears these bits when ownership cannot be preserved."}], "lastModified": "2026-04-24T19:04:01.207", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:uutils:coreutils:-:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "4A9AF9E4-E17C-48AD-8051-B49998618839"}], "operator": "OR"}]}], "sourceIdentifier": "security@ubuntu.com"}
