CVE-2021-22552 [MEDIUM] CWE-126 CVE-2021-22552: An untrusted memory read vulnerability in Asylo versions up to 0.6.1 allows an untrusted attacker to An untrusted memory read vulnerability in Asylo versions up to 0.6.1 allows an untrusted attacker to pass a syscall number in MessageReader that is then used by sysno() and can bypass validation. This can allow the attacker to read memory from within the secure enclave. We recommend updating to Asylo 0.6.3 or past https://github.com/google/asylo/com

CVE-2021-22549 [MEDIUM] CWE-823 CVE-2021-22549: An attacker can modify the address to point to trusted memory to overwrite arbitrary trusted memory.

The parameter size is unchecked allowing the attacker to read memory locations outside of the intended buffer size including memory addresses within the

CVE-2020-8940 [MEDIUM] CWE-120 CVE-2020-8940: An arbitrary memory read vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to An arbitrary memory read vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to make a call to enc_untrusted_recvmsg using an attacker controlled result parameter. The parameter size is unchecked allowing the attacker to read memory locations outside of the intended buffer size including memory addresses within the secure enclave.

CVE-2020-8941 [MEDIUM] CWE-120 CVE-2020-8941: An arbitrary memory read vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to An arbitrary memory read vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to make a call to enc_untrusted_inet_pton using an attacker controlled klinux_addr_buffer parameter. The parameter size is unchecked allowing the attacker to read memory locations outside of the intended buffer size including memory addresses within the s

CVE-2020-8944 [MEDIUM] CWE-120 CVE-2020-8944: An arbitrary memory write vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker t An arbitrary memory write vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to make a call to ecall_restore using the attribute output which fails to check the range of a pointer. An attacker can use this pointer to write to arbitrary memory addresses including those within the secure enclave We recommend upgrading past commit 3

CVE-2020-8943 [MEDIUM] CWE-120 CVE-2020-8943: An arbitrary memory read vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to An arbitrary memory read vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to make a call to enc_untrusted_recvfrom whose return size was not validated against the requested size. The parameter size is unchecked allowing the attacker to read memory locations outside of the intended buffer size including memory addresses within t

CVE-2020-8939 [MEDIUM] CWE-125 CVE-2020-8939: An out of bounds read on the enc_untrusted_inet_ntop function allows an attack to extend the result An out of bounds read on the enc_untrusted_inet_ntop function allows an attack to extend the result size that is used by memcpy() to read memory from within the enclave heap. We recommend upgrading past commit 6ff3b77ffe110a33a2f93848a6333f33616f02c4

CVE-2020-8936 [MEDIUM] CWE-125 CVE-2020-8936: An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make 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 enc

CVE-2020-8938 [MEDIUM] CWE-787 CVE-2020-8938: An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make 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.

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

CVE-2020-8905 [LOW] CWE-120 CVE-2020-8905: A buffer length validation vulnerability in Asylo versions prior to 0.6.0 allows an attacker to read A buffer length validation vulnerability in Asylo versions prior to 0.6.0 allows an attacker to read data they should not have access to. The 'enc_untrusted_recvfrom' function generates a return value which is deserialized by 'MessageReader', and copied into three different 'extents'. The length of the third 'extents' is controlled by the outside world,
