Heap memory corruption with RSA private key operation

Published: 7/2/2022Modified: 11/8/2023
Also known as:GHSA-735f-pg76-fxc4ALPINE-CVE-2022-2274RUSTSEC-2022-0033

Description

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. Note that on a vulnerable machine, proper testing of OpenSSL would fail and should be noticed before deployment.
