Public bug reported:

Packages that build-depend on rust-tar directly or indirectly may
contain vulnerable code.

Recently, rust-tar has been patched to fix a CVE
(https://www.cve.org/CVERecord?id=CVE-2026-33056). Most packages have
already been uploaded to the archive.

However, no-change rebuilds are still necessary for all packages that
either (1) build-depend on librust-tar-X.Y-dev or (2) on other
librust-$LIB-dev packages that, in turn, depend on librust-tar-X.Y-dev.

For example: rust-cargo-c on Noble does not vendor the tar crate.
However, it build-depends on librust-cargo-dev which, in turn, depends
on librust-tar-0.4-dev, which contained the vulnerability. Now that
rust-tar has been patched and uploaded to the archive, we need to
rebuild rust-cargo-c for it to pick up the fix.
