{"id":"GHSA-v24v-f45g-w7jf","summary":"Duplicate Advisory: uutils coreutils has a Time-of-Check to Time-of-Use (TOCTOU) race condition","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-239g-2685-54x3. This link is maintained to preserve external references.\n\n### Original Description\nThe install utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition during file installation. The implementation unlinks an existing destination file and then recreates it using a path-based operation without the O_EXCL flag. A local attacker can exploit the window between the unlink and the subsequent creation to swap the path with a symbolic link, allowing them to redirect privileged writes to overwrite arbitrary system files.","modified":"2026-09-10T03:50:44.788517644Z","published":"2026-04-22T18:31:45Z","withdrawn":"2026-07-06T19:54:01Z","database_specific":{"cwe_ids":["CWE-367"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-04-30T17:10:01Z","nvd_published_at":"2026-04-22T17:16:37Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35355"},{"type":"WEB","url":"https://github.com/uutils/coreutils/pull/10067"},{"type":"WEB","url":"https://github.com/uutils/coreutils/commit/b5bbabc18a1121908848d836f869a4e98eb63886"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"},{"type":"WEB","url":"https://github.com/uutils/coreutils/releases/tag/0.6.0"}],"affected":[{"package":{"name":"coreutils","ecosystem":"crates.io","purl":"pkg:cargo/coreutils"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.6.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-v24v-f45g-w7jf/GHSA-v24v-f45g-w7jf.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H"}]}
