Descriptions

yast2-security didn't use secure defaults to protect passwords. This became a problem on 2019-10-07 when configuration files that set secure settings were moved to a different location. As of the 20191022 snapshot the insecure default settings were used until yast2-security switched to stronger defaults in 4.2.6 and used the new configuration file locations. Password created during this time used DES password encryption and are not properly protected against attackers that are able to access the password hashes.

yast2-security no usó valores predeterminados seguros para proteger las contraseñas. Esto se convirtió en un problema el 07-10-2019 cuando los archivos de configuración que establecieron configuraciones seguras fueron movidas a una ubicación diferente. A partir de la instantánea 20191022, la configuración predeterminada no segura que fue usada hasta que yast2-security cambió a valores predeterminados más fuertes en la versión 4.2.6 y usó las nuevas ubicaciones del archivo de configuración. La contraseña creada durante este tiempo usó el cifrado de contraseña DES y no está protegida apropiadamente contra atacantes que son capaces de acceder a los hash de contraseña.
