    CVE-2020-8938

    An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to FromkLinuxSockAddr with attacker controlled content and size of klinux_addr which allows an attacker to write memory values from within the enclave. We recommend upgrading past commit a37fb6a0e7daf30134dbbf357c9a518a1026aa02
