CVE-2026-44604

Red Hat Red Hat Hardened Images, Pen Drive Powered by Red Hat Lightspeed, Red Hat build of Quarkus Native builder

A command injection vulnerability was discovered in the `rpmuncompress` utility of RPM. When extracting certain archive formats (ZIP, 7z, GEM) to a specified destination directory, the tool inserts the archive's top-level folder name into a shell command without properly sanitizing it. A specially crafted archive containing shell metacharacters in its folder name can execute arbitrary commands as the user running the extraction.
