Severity: High
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.
Taiwan-based network-attached storage (NAS) maker QNAP warned on Tuesday that most of its NAS devices are impacted by a high severity OpenSSL bug disclosed two weeks ago.
Attackers can exploit the vulnerability, tracked as CVE-2022-0778, to trigger a denial of service state and remotely crash unpatched devices.
