Descriptions

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.

En libzypp, en versiones anteriores a la 20170803, fue posible recuperar paquetes no firmados sin avisar al usuario. Esto podía resultar en que un atacante Man-in-the-Middle (MitM) o servidores maliciosos inyectasen paquetes RPM maliciosos en el sistema de un usuario.
