Descriptions

Trusted Firmware-A through 2.8 has an out-of-bounds read in the X.509 parser for parsing boot certificates. This affects downstream use of get_ext and auth_nvctr. Attackers might be able to trigger dangerous read side effects or obtain sensitive information about microarchitectural state.

Trusted Firmware-A hasta su versión 2.8 tiene una lectura fuera de los límites en el analizador X.509 para analizar los certificados de arranque. Esto afecta el uso posterior de get_ext y auth_nvctr. Los atacantes podrían desencadenar efectos secundarios de lectura peligrosos u obtener información confidencial sobre el estado de la microarquitectura.
