Descriptions

The decoupled download and installation steps in libzypp before 17.5.0 could lead to a corrupted RPM being left in the cache, where a later call would not display the corrupted RPM warning and allow installation, a problem caused by malicious warnings only displayed during download.

Los pasos de descarga e instalación desacoplados en libzypp en versiones anteriores a la 17.5.0 podría conducir a que un RPM corrupto se deje en la caché, en la que una llamada posterior no mostraría el aviso de RPM corrupto y permite la instalación. Este problema está provocado por avisos maliciosos que solo se muestran durante la descarga.
