Summary
OpenSSL is prone to a buffer overflow vulnerability in the RSA implementation for AVX512IFMA capable CPUs.
Insight
Insight
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.
Affected Software
Affected Software
OpenSSL prior to version 1.1.1q and version 3.0.4.
Detection Method
Detection Method
Checks if a vulnerable version is present on the target host.
Solution
Solution
Update to version 1.1.1q, 3.0.5 or later.
