Name of the Vulnerable Software and Affected Versions
pyp2spec versions prior to 0.14.1
Description
pyp2spec writes PyPI package metadata, such as the summary field, into generated spec files without escaping RPM macro directives. When a packager uses tools like
rpmbuild -bs, rpmbuild --nobuild, or rpm -q --specfile, these directives are evaluated, allowing a malicious package to execute arbitrary commands on the build machine. This execution occurs during spec parsing, meaning a full build is not required for compromise. Potential attack vectors include typosquatting or targeting packages under Fedora review, which could lead to the compromise of sensitive credentials such as dist-git SSH keys, Koji build credentials, and Bodhi update credentials.Recommendations
Update to version 0.14.1.
