OpenSSL has issued an urgent advisory to warn of a memory corruption vulnerability that exposes servers to remote code execution attacks.
The vulnerability, tracked as CVE-2022-2274, was introduced in OpenSSL 3.0.4 and could potentially allow malicious hackers to launch remote code attacks on unpatched SSL/TLS server side devices.
The open source group rates this a “high-severity” issue and urged users to upgrade to OpenSSL 3.0.5.

Details from the OpenSSL advisory:
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.
OpenSSL 1.1.1 and 1.0.2 are not affected by this issue, according to the advisory.
