Examining data/smem-1.5/smemcap.c

FINAL RESULTS:

data/smem-1.5/smemcap.c:34:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(header, "%s", path);
data/smem-1.5/smemcap.c:88:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(path, "%s/%s", sub, name);
data/smem-1.5/smemcap.c:22:2:  [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 data[512];
data/smem-1.5/smemcap.c:29:2:  [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 header[512];
data/smem-1.5/smemcap.c:35:2:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	sprintf(header + 100, "%07o", mode & 0777);
data/smem-1.5/smemcap.c:36:2:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	sprintf(header + 108, "%07o", uid);
data/smem-1.5/smemcap.c:37:2:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	sprintf(header + 116, "%07o", gid);
data/smem-1.5/smemcap.c:38:2:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	sprintf(header + 124, "%011o", size);
data/smem-1.5/smemcap.c:39:2:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	sprintf(header + 136, "%07o", mtime);
data/smem-1.5/smemcap.c:40:2:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	sprintf(header + 148, "        %1d", type);
data/smem-1.5/smemcap.c:45:2:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
	sprintf(header + 148, "%06o", sum);
data/smem-1.5/smemcap.c:58:7:  [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).
	fd = open(path, O_RDONLY);
data/smem-1.5/smemcap.c:87:2:  [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 path[256];
data/smem-1.5/smemcap.c:65:7:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
		r = read(fd, cur->data, 512);
