FINAL RESULTS:

data/pd-cxc-0.5.2/ascseq.c:61:5:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
    strcat(x->x_bla,s->s_name);

  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
    strcat(x->x_bla,tmp);
data/pd-cxc-0.5.2/hex2dec.c:29:5:  [4] (format) sprintf:
  Potential format string problem (CWE-134). Make format string constant.
    sprintf(buf, x->x_format->s_name, (int)f);
data/pd-cxc-0.5.2/hex2dec.c:36:5:  [4] (format) sprintf:
  Potential format string problem (CWE-134). Make format string constant.

  sprintf(name,"%s","/proc/cpuinfo");
data/pd-cxc-0.5.2/proc.c:78:10:  [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.
    ac = fscanf(fp,"%s\t: %f",name,&restf);
data/pd-cxc-0.5.2/proc.c:126:3:  [4] (buffer) sprintf:

  vsnprintf.
  sprintf(name,"/proc/%s",s->s_name);
data/pd-cxc-0.5.2/proc.c:147:12:  [4] (buffer) fscanf:
  The scanf() family's %s operation, without a limit specification, permits

  different input function.
      ac = fscanf(fp,"%s\t: %f",name,&restf);

data/pd-cxc-0.5.2/ENV.c:42:9:  [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.

  maximum possible length.

data/pd-cxc-0.5.2/ascwave.c:12:19:  [2] (misc) fopen:
  Check when opening files - can an attacker redirect it (via symlinks),

  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
