FINAL RESULTS:

data/ruby-pygments.rb-1.2.1/test/test_data.c:298:5:  [4] (format) vsnprintf:
  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.
    vsnprintf(msg, sizeof(msg), fmt, ap);
data/ruby-pygments.rb-1.2.1/test/test_data.c:2448:5:  [4] (format) snprintf:
  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.
    snprintf(buf,1024*16,ascii_logo,
data/ruby-pygments.rb-1.2.1/test/test_data.c:2498:5:  [3] (random) srand:
  This function is not sufficiently random for security-related functions
  such as key and nonce creation (CWE-327). Use a more secure technique for
  acquiring random values.

  maximum possible length.

  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
