During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability."},{"lang":"es","value":"Se encontró un fallo en grub2 en versiones anteriores a 2.06. Durante la inicialización del dispositivo USB, los descriptores se leen con muy poca comprobación de límites y se supone que el dispositivo USB proporciona valores saneados. Si es explotada
