openssl-src heap memory corruption with RSA private key operation

Critical severity GitHub Reviewed Published Jul 2, 2022 to the GitHub Advisory Database • Updated Jun 13, 2023

Package

cargo openssl-src (Rust)

Affected versions

>= 300.0.8, < 300.0.9

Patched versions

300.0.9

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.
