FINAL RESULTS:

data/postgresql-mysql-fdw-2.5.5/mysql_fdw.c:460:2:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
	char		timeout[255];
data/postgresql-mysql-fdw-2.5.5/mysql_fdw.c:512:3:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
		sprintf(timeout, "SET wait_timeout = %d", wait_timeout);
data/postgresql-mysql-fdw-2.5.5/mysql_fdw.c:519:3:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
		sprintf(timeout, "SET interactive_timeout = %d", interactive_timeout);
