Frequently Asked Questions
Which systems and workflows are most exposed?
Systems using the listed Rocky Linux RPM components are exposed when RPM utilities process attacker-controlled filenames, tarballs or tar member names, or crafted .gem filenames. The affected paths include rpmuncompress and rpmbuild operations involving tarball handling.
What does an attacker need to exploit these issues?
The supplied CVSS vector indicates local access and user interaction are required, while no privileges are required. Exploitation involves getting a user or automated RPM workflow to process crafted input containing unescaped or macro-expanded names.
How can I identify potentially affected activity before applying updates?
Review whether systems use rpmuncompress, rpmuncompress -x, or rpmbuild -t operations on untrusted packages, tarballs, archives, or .gem files. Pay particular attention to inputs whose filenames or archive member names originate outside the trusted build or package-source process.
