CVE-2020-8936: Arbitrary enclave memory overwrite vulnerability in ECall ecall_restore

First published: Tue Dec 15 2020(Updated: )

An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to UntrustedCall. UntrustedCall failed to validate the buffer range within sgx_params and allowed the host to return a pointer that was an address within the enclave memory. This allowed an attacker to read memory values from within the enclave.
