"The remote OT asset is affected by a vulnerability.");
  script_set_attribute(attribute:"description", value:
"An invalid pointer dereference on read can be triggered when an
application tries to check a malformed DSA public key by the
EVP_PKEY_public_check() function. This will most likely lead to an
application crash. This function can be called on public keys supplied
from untrusted sources which could allow an attacker to cause a denial
of service attack. The TLS implementation in OpenSSL does not call
this function but applications might call the function if there are
additional security requirements imposed by standards such as FIPS
140-3.

This plugin only works with Tenable.ot.
