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. Therefore, you can fix this in Fedora at any time by simply rebuilding trustee-guest-components. I’m not going to do that now because rust-sig is not a co-maintainer.
