Description Jon Moroney 2026-03-20 17:56:21 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.
Comment 1 Ben Beasley 2026-03-22 08:09:16 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. However, since rust-zincati “temporarily” (for the past five years) uses vendored Rust crate dependencies, its maintainers would need to fix this separately within the package’s dependency bundle.
