Descriptions

In Gentoo Portage before 3.0.47, there is missing PGP validation of executed code: the standalone emerge-webrsync downloads a .gpgsig file but does not perform signature verification. Unless emerge-webrsync is used, Portage is not vulnerable.

En Gentoo Portage anterior a 3.0.47, falta la validación PGP del código ejecutado: el emerge-webrsync independiente descarga un archivo .gpgsig pero no realiza la verificación de firma.
