CVE-2017-13786

Estado: ModificadaMedia (4.6)—

Se ha descubierto un problema en algunos productos Apple. Se han visto afectadas las versiones de macOS anteriores a la 10.13.1. El problema afecta al componente "APFS". No restringe correctamente el tiempo de asignación DMA de los búfers de descifrado FileVault, lo que permite que atacantes lean datos APFS en texto claro mediante un adaptador Thunderbolt manipulado.
