Comment 1 Ben Beasley 2026-03-22 08:57:18 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. 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.
Comment 2 Uri Lublin 2026-08-13 08:32:03 UTC 
Fedora trustee-guest-components does not use the tar crate.

fedpkg clone -a trustee-guest-components
cd trustee-guest-components
fedpkg sources
fedpkg prep
cd trustee-guest-component*build/guest-component*/
cargo tree | grep tar # shows unrelated "target"

image-rs member does use the tar crate, but is being removed in Fedora
