Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
pyp2spec before 0.14.1 writes package metadata such as the summary field into generated spec files without escaping RPM macro directives. A malicious package can run arbitrary commands on the build machine when rpm tools such as rpmbuild process the generated spec, even without a full build. Upgrade to 0.14.1.
