https://notcve.org/view.php?id=CVE-2021-4209
A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances. Se ha encontrado un fallo de desreferencia de puntero NULL en GnuTLS.
