CVE-2017-18018 (GCVE-0-2017-18018)

Vulnerability from cvelistv5 – Published: 2018-01-04 04:00 – Updated: 2025-06-09 15:57

Summary

In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX "-R -L" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition.

Severity
