The command creates parent directories and subsequently performs a second path resolution to create the target file, neither of which is anchored to a directory file descriptor. An attacker with concurrent write access can replace a path component with a symbolic link between these operations, redirecting the privileged write to an arbitrary file system location."}], "lastModified": "2026-04-27T12:27:28.787", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "7F64F6A4-00A5-4FB8-BB51-21F475C11FF2", "versionEndExcluding": "0.7.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@ubuntu.com"}
