Overview

node is a JavaScript runtime built on Chrome's V8 JavaScript engine.

Affected versions of this package are vulnerable to Improper Certificate Validation. It is possible to trigger an assertion on a TLS server with a malformed certificate string. X509V3_EXT_print can return value different from 1 if the X509 extension does not support printing to a buffer. Instead of failing with an unrecoverable assertion. This vulnerability can be exploited by a user that can remotely connect to a TLS server and supply an invalid certificate, causing the server to crash. As such, this vulnerability could result in a denial-of-service vulnerability.
