https://notcve.org/view.php?id=CVE-2021-4044
14 Dec 2021 — Internally libssl in OpenSSL calls X509_verify_cert() on the client side to verify a certificate supplied by a server. That function may return a negative return value to indicate an internal error (for example out of memory). Such a negative return value is mishandled by OpenSSL and will cause an IO function (such as SSL_connect() or SSL_do_handshake()) to not indicate success and a subsequent call to SSL_get_error() to return the value SSL_ERROR_WANT_RETRY_VERIFY. This return value is only supposed to be ... • https://github.com/phirojshah/CVE-2021-4044 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

CVE-2021-43803 – Unexpected server crash in Next.js
https://notcve.org/view.php?id=CVE-2021-43803
09 Dec 2021 — Next.js is a React framework. In versions of Next.js prior to 12.0.5 or 11.1.3, invalid or malformed URLs could lead to a server crash. In order to be affected by this issue, the deployment must use Next.js versions above 11.1.0 and below 12.0.5, Node.js above 15.0.0, and next start or a custom server. Deployments on Vercel are not affected, along with similar environments where invalid requests are filtered before reaching Next.js. Versions 12.0.5 and 11.1.3 contain patches for this issue. • https://github.com/vercel/next.js/commit/6d98b4fb4315dec1badecf0e9bdc212a4272b264 • CWE-20: Improper Input Validation •

CVE-2021-3450 – CA certificate check bypass with X509_V_FLAG_X509_STRICT
https://notcve.org/view.php?id=CVE-2021-3450
25 Mar 2021 — The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten.
