Comment 1 Ben Beasley 2026-03-22 08:24:50 UTC
More information is available at https://www.cve.org/CVERecord?id=CVE-2026-33056. This flaw is fixed in version 0.4.45 of the tar crate. Updates for rust-tar-0.4.45 are in testing for all Fedora and EPEL branches, and buildroot overrides are active. Since rust-sig is a co-maintainer on this package, I plan to rebuild it and issue updates for all branches.
