CVSS: 7.5EPSS: 0%CPEs: 28EXPL: 0CVE-2021-4044 – Invalid handling of X509_verify_cert() internal errors in libssl
https://notcve.org/view.php?id=CVE-2021-4044
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 returned by OpenSSL if the application has previously called SSL_CTX_set_cert_verify_callback(). Since most applications do not do this the SSL_ERROR_WANT_RETRY_VERIFY return value from SSL_get_error() will be totally unexpected and applications may not behave correctly as a result. • https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=758754966791c537ea95241438454aa86f91f256 https://security.netapp.com/advisory/ntap-20211229-0003 https://www.openssl.org/news/secadv/20211214.txt • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2021-43803 – Unexpected server crash in Next.js
https://notcve.org/view.php?id=CVE-2021-43803
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 https://github.com/vercel/next.js/pull/32080 https://github.com/vercel/next.js/releases/tag/v11.1.3 https://github.com/vercel/next.js/releases/v12.0.5 https://github.com/vercel/next.js/security/advisories/GHSA-25mp-g6fv-mqxx • CWE-20: Improper Input Validation •
