Given our ongoing research on Intel SGX here in the LSDS group at Imperial College London, a question that occurred to us immediately on first hearing of the recent Meltdown and Spectre attacks is what are the security implications of speculative execution side channels for Intel SGX. " The security flaw is noted under CVE-2019-11157 and was first reported to Intel back in June of this year under the company's bug bounty program. It is a development of the previously known Meltdown security vulnerability. 3 has been updated to include OpenSSL 1. Breach Bug CVE Cyber Security Malvertise Malware RCE Vulnerability. If you need to use the Intel® SGX platform service, install the Intel® Management Engine (Intel® ME) software components. However, the problem of vulnerability in SGX and the SSD continues to be raised [firmware_isolated, lviattack, foreshadow]. The vulnerability affects Intel, IBM and a limited number of ARM CPUs. Researchers have demonstrated using Intel's Software Guard Extensions. USENIX Security'18. Improper input validation in the Intel(R) SGX Platform Software for Windows* may allow an authenticated user to potentially enable a denial of service via local access. In fact, Intel SGX flushes the uOp cache automatically on enclave entry/exit, so using SGX will also mitigate the vulnerability. SGAxe, a SGX vulnerability, extends a speculative execution attack on cache, leaking content of the enclave. to hide malware and steal cryptographic keys from inside SGX's protected enclave:. by Samuel Haig. Nevertheless, a vulnerability that allows access to data from SGX enclaves is a serious matter. Please see the full list of affected products here. 2 for Linux, version 2. As the industry has patched for Spectre and. Another list:. Intel® SGX and Side-Channels. The standard Foreshadow variant (Reference CVE-2018-3615) targets Intel's Software Guard Extensions (SGX), which is new technology designed by intel to help keep user data from falling into the wrong hands, even if the whole system comes under attack. Intel Corporation Hillsboro, OR 3. The first vulnerability known as Foreshadow or CVE-2018-3615 is used to extract data from an Intel SGX (Software Guard Extensions) secure enclave (area) by creating a shadow copy of the SGX protected data but that copy does not have the protection of SGX and can be read/accessed by the attacker.
