Memory overread secure enclave in Asylo 0.6.2
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 secu…

Enclave memory overwrite/overread vulnerability in Asylo UntrustedCacheMalloc::GetBuffer
An attacker can modify the pointers in enclave memory to overwrite arbitrary memory addresses within the secure enclave. It is recommended to update past 0.6.3 or git commit https://github.com/google/asylo/commit/a47ef55db2337d29de19c50cd29b0deb2871d31c

Arbitrary enclave memory overwrite vulnerability in Asylo TrustedPrimitives::UntrustedCall
An attacker can modify the address to point to trusted memory to overwrite arbitrary trusted memory. It is recommended to update past 0.6.2 or git commit https://github.com/google/asylo/commit/53ed5d8fd8118ced1466e509606dd2f473707a5c

Medium 6.5
Arbitrary enclave memory overread vulnerability in Asylo TrustedPrimitives::UntrustedCall
An attacker can change the pointer to untrusted memory to point to trusted memory region which causes copying trusted memory to trusted memory, if the latter is later copied out, it allows for reading of memory regions from the trusted region. It is recommend…

Unchecked buffer overrun in ecall_restore
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 m…

Unchecked buffer overrun in enc_untrusted_read
An arbitrary memory read vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to make a call to enc_untrusted_read whose return size was not validated against the requrested size. The parameter size is unchecked allowing the attacker to re…

Unchecked buffer overrun in enc_untrusted_recvfrom
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…

Unchecked buffer overrun in enc_untrusted_inet_pton
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 rea…

Unchecked buffer overrun in enc_untrusted_recvmsg
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 locat…

Out of Bounds read in Asylo
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

Arbitrary enclave memory location write from untrusted environment
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 enc…

Arbitrary enclave memory location write from untrusted environment
An arbitrary memory overwrite vulnerability in Asylo versions up to 0.6.0 allows an attacker to make a host call to enc_untrusted_create_wait_queue that uses a pointer queue that relies on UntrustedLocalMemcpy, which fails to validate where the pointer is loc…

Arbitrary enclave memory overwrite vulnerability in ECall ecall_restore
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…

Arbitrary trusted memory overwrite vulnerability in Asylo
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…
