NVD Description
Note: Versions mentioned in the description apply only to the upstream rpm-build-libs package and not the rpm-build-libs package as distributed by RHEL.
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.
