FINAL RESULTS:

data/mousetweaks-3.32.0/src/mt-pidfile.c:50:12:  [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.
    static char fn[512];

  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.
    static char txt[256];
data/mousetweaks-3.32.0/src/mt-pidfile.c:99:15:  [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).

  Check buffer boundaries if used in a loop including recursive loops

data/mousetweaks-3.32.0/src/mt-pidfile.c:196:9:  [1] (access) umask:
  Ensure that umask is given most restrictive possible setting (e.g., 066 or

data/mousetweaks-3.32.0/src/mt-pidfile.c:216:9:  [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).
    l = strlen (t);
data/mousetweaks-3.32.0/src/mt-pidfile.c:240:5:  [1] (access) umask:
