Kerentanan Use of Out-of-range Pointer Offset pada google asylo. Skor CVSS 3.1 9.6 (Critical) menurut NVD.

Deskripsi (NVD)

An arbitrary memory overwrite vulnerability in the trusted memory of Asylo exists in versions prior to 0.6.0. As the ecall_restore function fails to validate the range of the output_len pointer, an attacker can manipulate the tmp_output_len value and write to an arbitrary location in the trusted (enclave) memory. We recommend updating Asylo to version 0.6.0 or later.
