  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.

  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
