Descripción

*** Pendiente de traducción *** An invalid pointer dereference on read can be triggered when an<br /> application tries to check a malformed DSA public key by the<br /> EVP_PKEY_public_check() function. This will most likely lead<br /> to an application crash. This function can be called on public<br /> keys supplied from untrusted sources which could allow an attacker<br /> to cause a denial of service attack.<br /> <br /> The TLS implementation in OpenSSL does not call this function<br /> but applications might call the function if there are additional<br /> security requirements imposed by standards such as FIPS 140-3.
