GSD-2022-2274
Vulnerability from gsd - Updated: 2023-12-13 01:19Details
The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X86_64 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a consequence of the memory corruption an attacker may be able to trigger a remote code execution on the machine performing the computation. SSL/TLS servers or other servers using 2048 bit RSA private keys running on machines supporting AVX512IFMA instructions of the X86_64 architecture are affected by this issue.

"description": "In OpenSSL version 3.0.4 a heap buffer overflow exists in the AVX512 support that can be attacked via network resulting in code execution. This is reachable via four code paths: RSAZ 1024, RSAZ 512, Dual 1024 RSAZ, and Default constant-time Montgomery modular exponentiation. Please note this issue is especially serious as OpenSSL 3.0.4 contains a security fix for CVE-2022-2068 which allows arbitrary code execution. This means that all users of OpenSSL 3 are affected by a number of serious security vulnerabilities. Intel AXV-512 support is present in Intel CPUs releases including Knights Landing (Xeon Phi x200, 2016), Knights Mill (Xeon Phi x205, 2017), Skylake-SP, Skylake-X (2017), Cannon Lake (2018), Cascade Lake (2019), Cooper Lake (2020), Ice Lake (2019), Tiger Lake (2020), Rocket Lake (2021). Please note that on Alder Lake (2021) AVX-512 is not officially supported, but can be enabled on some motherboards with some BIOS versions. For AMD all Zen4 CPUs contain AVX-512 support.",
