OpenSSL has issued an pressing advisory to warn of a reminiscence corruption vulnerability that exposes servers to distant code execution assaults.

The vulnerability, tracked as CVE-2022-2274, was launched in OpenSSL 3.0.four and will probably permit malicious hackers to launch distant code assaults on unpatched SSL/TLS server aspect units.

The open supply group charges this a “high-severity” concern and urged customers to improve to OpenSSL 3.0.5.

Particulars from the OpenSSL advisory:

The OpenSSL 3.0.four launch launched a severe bug within the RSA implementation for X86_64 CPUs supporting the AVX512IFMA directions.

This concern makes the RSA implementation with 2048 bit non-public keys incorrect on such machines and reminiscence corruption will occur through the computation. As a consequence of the reminiscence corruption an attacker might be able to set off a distant code execution on the machine performing the computation.

SSL/TLS servers or different servers utilizing 2048 bit RSA non-public keys working on machines supporting AVX512IFMA directions of the X86_64 structure are affected by this concern.

OpenSSL 1.1.1 and 1.0.2 usually are not affected by this concern, based on the advisory.
