It was found that the GnuTLS implementation of HMAC-SHA-384 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets.

Demo Examples

Use of a Broken or Risky Cryptographic Algorithm

CWE-327

These code examples use the Data Encryption Standard (DES).


               
EVP_des_ecb();

               
des.initEncrypt(key2);

               
}
return $encryptedPassword;

Once considered a strong algorithm, DES now regarded as insufficient for many applications. It has been replaced by Advanced Encryption Standard (AES).
