CVE-2021-20197 (GCVE-0-2021-20197)

Vulnerability from cvelistv5 – Published: 2021-03-26 16:47 – Updated: 2025-12-03 15:08

Summary

There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink.
