FINAL RESULTS:

data/libgnatcoll-19/src/executable_path.c:59:12:  [5] (race) readlink:
  This accepts filename arguments; if an attacker can move those files or
  change the link content, a race condition results. Also, it does not
  terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
    return readlink("/proc/self/exe", buffer, (size_t) size);
data/libgnatcoll-19/src/gnatcoll_support.c:135:9:  [5] (race) chmod:
  This accepts filename arguments; if an attacker can move those files, a
  race condition results. (CWE-362). Use fchmod( ) instead.
        chmod (file, statbuf.st_mode | S_IREAD);
data/libgnatcoll-19/src/gnatcoll_support.c:137:9:  [5] (race) chmod:
  This accepts filename arguments; if an attacker can move those files, a
  race condition results. (CWE-362). Use fchmod( ) instead.
        chmod (file, statbuf.st_mode & (~S_IREAD));
data/libgnatcoll-19/src/gnatcoll_support.c:172:12:  [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.
  result = getenv ("TMPDIR");
data/libgnatcoll-19/src/gnatcoll_support.c:177:12:  [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.
  result = getenv ("TMP");
data/libgnatcoll-19/src/gnatcoll_support.c:184:12:  [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.
  result = getenv ("TEMP");
data/libgnatcoll-19/src/getRSS.c:57:13:  [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).
	if ( (fd = open( "/proc/self/psinfo", O_RDONLY )) == -1 )
data/libgnatcoll-19/src/getRSS.c:112:13:  [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).
	if ( (fp = fopen( "/proc/self/statm", "r" )) == NULL )
data/libgnatcoll-19/src/executable_path.c:38:16:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
        return strlen(buffer);
data/libgnatcoll-19/src/getRSS.c:59:7:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	if ( read( fd, &psinfo, sizeof(psinfo) ) != sizeof(psinfo) )
