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.
