Frequently Asked Questions

1

Who is most exposed to these issues?

Systems where users run rpmbuild with tarball-based build inputs are most exposed, particularly when tarball paths or archive member names can be influenced by an untrusted party. The affected package set includes rpm, rpm-build, rpm-build-libs, python3-rpm, and their listed debuginfo packages.

2

What input is needed to trigger the vulnerabilities?

One issue involves an unescaped tarball path processed by rpmbuild -t. The other involves a crafted tar archive member name that can cause macro injection through getTarSpec().

3

Can affected installations be identified from the advisory alone?

No. The advisory identifies affected Rocky Linux package names but does not provide fixed or affected version numbers, so package-version status cannot be determined from the supplied information alone.
