FINAL RESULTS:

data/matita-0.99.3/components/binaries/matitaprover/TreeLimitedRun.c:414:17:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
                sprintf(ErrorMessage,
data/matita-0.99.3/components/binaries/matitaprover/TreeLimitedRun.c:809:13:  [4] (shell) execvp:
  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.
            execvp(argv[ArgOffset+3],argv+ArgOffset+3);
data/matita-0.99.3/components/binaries/matitaprover/TreeLimitedRun.c:36:9:  [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.
typedef char String[STRING_LENGTH];
data/matita-0.99.3/components/binaries/matitaprover/TreeLimitedRun.c:165:26:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).

data/matita-0.99.3/components/binaries/matitaprover/TreeLimitedRun.c:166:13:  [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.

data/matita-0.99.3/components/binaries/matitaprover/TreeLimitedRun.c:167:29:  [2] (misc) fopen:
  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).
