title: libzypp accepts unsigned packages even when configured to check signatures
description: In libzypp before 20170803 it was possible to retrieve unsigned packages without a warning to the user which could lead to man in the middle or malicious servers to inject malicious RPM packages into a users system.
problem types: Missing UI interaction when using unsigned packages could lead to use of malicious packages.
