Name of the Vulnerable Software and Affected Versions Arm Mbed TLS versions prior to 2.23.0 Description The issue is related to a side channel in modular exponentiation, which could disclose an RSA private key used in a secure enclave. This is due to a dependency of the instruction timing on the...
Special Register Buffer Data Sampling Advisory
Summary: A potential security vulnerability in some Intel® Processors may allow information disclosure. Intel is releasing firmware updates to mitigate this potential vulnerability. Vulnerability Details: CVEID: CVE-2020-0543 Description: Incomplete cleanup from specific special register read...
CVE-2020-10932
An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...

CVE-2020-10932
CVE-2020-10932 affects Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker able to obtain precise side‑channel measurements (often in compromised environments like SGX enclaves) can recover the long‑term ECDSA private key by exploiting side channels in scalar multiplication, convertin...

Mbed TLS -- Side channel attack on ECDSA
Manuel Pégourié-Gonnard reports: An attacker with access to precise enough timing and memory access information typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world can fully recover an ECDSA private key after observing a number of signature...
Updated mbedtls packages fix security vulnerabilities
Updated mbedtls packages fix security vulnerabilities: If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported. Found by Alejandro Cabrera Aldaya and Billy...
hw: Intel SGX information leak
A flaw was found in the implementation of SGX around the access control of protected memory. This flaw allows a local attacker of a system with SGX enabled and an affected intel GPU with the ability to execute code to interpret the contents of the SGX protected memory...
FreeBSD : Mbed TLS -- Cache attack against RSA key import in SGX (056ea107-5729-11ea-a2f3-001cc0382b2f)
Janos Follath reports : If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported. The attack only requires access to fine grained measurements to cache usage...
New ‘CacheOut’ Attack Targets Intel CPUs
Researchers have identified a new speculative execution type attack, dubbed CacheOut, that could allow attackers to trigger data leaks from most Intel CPUs. The more serious of the two bugs, revealed Monday, is rated medium severity by Intel, who said fixes for both flaws are on the way. The more...
New 'CacheOut' Attack Leaks Data from Intel CPUs, VMs and SGX Enclave
Another month, another speculative execution vulnerability found in Intel processors. If your computer is running any modern Intel CPU built before October 2018, it's likely vulnerable to a newly discovered hardware issue that could allow attackers to leak sensitive data from the OS kernel,...
