Examining data/pcf2bdf-1.05/pcf2bdf.cc

FINAL RESULTS:

data/pcf2bdf-1.05/pcf2bdf.cc:15:11:  [4] (shell) popen:
  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.
#  define popen _popen
data/pcf2bdf-1.05/pcf2bdf.cc:600:5:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    sprintf(buf, "gzip -dc %s", ifilename); // TODO
data/pcf2bdf-1.05/pcf2bdf.cc:601:11:  [4] (shell) popen:
  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.
    ifp = popen(buf, "r");
data/pcf2bdf-1.05/pcf2bdf.cc:583:11:  [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).
    ifp = fopen(ifilename, "rb");
data/pcf2bdf-1.05/pcf2bdf.cc:599:5:  [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.
    char buf[1024];
data/pcf2bdf-1.05/pcf2bdf.cc:610:11:  [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).
    ofp = fopen(ofilename, "wb");
data/pcf2bdf-1.05/pcf2bdf.cc:249:11:  [1] (buffer) fgetc:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  int a = fgetc(ifp);
