FINAL RESULTS:

data/comptty-1.0.1/src/main.cxx:123:5:  [4] (shell) execlp:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
				execlp(browsers[i], browsers[i], url, (char*)0);
data/comptty-1.0.1/src/main.cxx:139:11:  [4] (shell) ShellExecute:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
	if ((int)ShellExecute(NULL, "open", url, NULL, NULL, SW_SHOWNORMAL) <= 32)
data/comptty-1.0.1/src/main.cxx:162:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf (title, "comptty %s", comptty_VERSION);
data/comptty-1.0.1/src/main.cxx:103:3:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
		getenv("FLDIGI_BROWSER"), // valid for any OS - set by user
data/comptty-1.0.1/src/main.cxx:108:3:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
		getenv("FLDIGI_BROWSER"), // force use of spec'd browser
data/comptty-1.0.1/src/main.cxx:109:3:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
		getenv("BROWSER"),        // most Linux distributions
data/comptty-1.0.1/src/comp_tty.cxx:14:10:  [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.
unsigned char BaudotTable[256];
data/comptty-1.0.1/src/comp_tty.cxx:85:5:  [2] (misc) open:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
	f1.open(ref_file.c_str(), ios::binary);
data/comptty-1.0.1/src/comp_tty.cxx:94:5:  [2] (misc) open:

  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).

  Statically-sized arrays can be improperly restricted, leading to potential

  functions that limit length, or ensure that the size is larger than the
  maximum possible length.

data/comptty-1.0.1/src/main.cxx:89:1:  [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
