CVE-2023-23919

A cryptographic vulnerability exists in Node.js <19.2.0, <18.14.1, <16.19.1, <14.21.3 that in some cases did does not clear the OpenSSL error stack after operations that may set it. This may lead to false positive errors during subsequent cryptographic operations that happen to be on the same thread. This in turn could be used to cause a denial of service.

This vulnerability has been rated as moderate by Redhat for several reasons,first and foremost being that in order for the stack to crash,same thread would have to be used by the application which is a complexity outside the hands of attacker because in node.js workloads may be isolated or not happen sequentially on the same thread, reducing exposure,moreover the exploitation might lead to denial of service and poses no threat to confidentiality or integrity of the system.
