This function can be called on public\nkeys supplied from untrusted sources which could allow an attacker\nto cause a denial of service attack.\nThe TLS implementation in OpenSSL does not call this function\nbut applications might call the function if there are additional\nsecurity requirements imposed by standards such as FIPS 140-3.", "A flaw was found in OpenSSL.
