Node.js is an open-source, cross-platform, JavaScript runtime environment, it executes JavaScript code outside of a browser.
Security Fix(es):
A security vulnerability has been identified in all supported versions
of OpenSSL related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial-of-service (DoS) attack on affected systems.
Policy processing is disabled by default but can be enabled by passing
the -policy' argument to the command line utilities or by calling the
X509VERIFYPARAMset1policies()' function.(CVE-2023-0464)
Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks.
Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether.
Policy processing is disabled by default but can be enabled by passing
the -policy' argument to the command line utilities or by calling the
X509VERIFYPARAMset1policies()' function.(CVE-2023-0465)
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.(CVE-2023-44487)
