FINAL RESULTS:

data/libvdeslirp-0.1.0/libvdeslirp.c:132:5:  [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 cmd[cmdlen];
data/libvdeslirp-0.1.0/libvdeslirp.c:131:21:  [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).
				size_t cmdlen = strlen(preq->ptrarg) + 8;
data/libvdeslirp-0.1.0/libvdeslirp.c:168:12:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
			rval =  read(preq->pipefd[APPSIDE],&rval,sizeof(rval));
data/libvdeslirp-0.1.0/libvdeslirp.c:389:17:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
			size_t len = read(slirp->channel[DAEMONSIDE], buf, JUMBOMTU);
data/libvdeslirp-0.1.0/libvdeslirp.c:505:9:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
	return read(slirp->channel[APPSIDE], buf, count);
