CVE-2020-8904 (GCVE-0-2020-8904)

Vulnerability from cvelistv5 – Published: 2020-08-12 18:20 – Updated: 2024-09-16 23:21

Title
Arbitrary trusted memory overwrite vulnerability in Asylo
Summary
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.
Severity
