FINAL RESULTS:

data/lxtask-0.1.10/src/utils.c:119:9:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
        sprintf( buf, "%u %s", ( guint ) size, unit );
data/lxtask-0.1.10/src/utils.c:123:5:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    sprintf( buf, "%.1f %s", val, unit );
data/lxtask-0.1.10/src/xfce-taskmanager-linux.c:145:3:  [4] (buffer) sscanf:
  The scanf() family's %s operation, without a limit specification, permits
  buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
  different input function.

data/lxtask-0.1.10/src/xfce-taskmanager-linux.c:243:10:  [4] (buffer) fscanf:
  The scanf() family's %s operation, without a limit specification, permits
  buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
  different input function. If the scanf format is influenceable by an
  attacker, it's exploitable.
