Examining data/pstack-1.3.1/pstack.c

FINAL RESULTS:

data/pstack-1.3.1/pstack.c:485:13:  [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).
  if ((fd = open(fname, O_RDONLY)) < 0)
data/pstack-1.3.1/pstack.c:603:3:  [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[256];
data/pstack-1.3.1/pstack.c:607:3:  [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(buf, "/proc/%d/exe", pid);
data/pstack-1.3.1/pstack.c:711:8:  [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.
static char cmd[128];
data/pstack-1.3.1/pstack.c:717:3:  [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(cmd, "/proc/%d/cmdline", pid);
data/pstack-1.3.1/pstack.c:718:13:  [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).
  if ((fd = open(cmd, O_RDONLY)) >= 0 &&
data/pstack-1.3.1/pstack.c:724:7:  [2] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused). Risk is low because the source is a constant string.
      strcpy(&cmd[sizeof(cmd) - 4], "...");
data/pstack-1.3.1/pstack.c:726:27:  [2] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused). Risk is low because the source is a constant string.
  if (fd < 0 || len <= 0) strcpy(cmd, "(command line?)");
data/pstack-1.3.1/pstack.c:435:9:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    if (read(fd, &shdr, hdr->e_shentsize) != hdr->e_shentsize)
data/pstack-1.3.1/pstack.c:446:21:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).

data/pstack-1.3.1/pstack.c:452:11:  [1] (buffer) read:

data/pstack-1.3.1/pstack.c:466:21:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops

data/pstack-1.3.1/pstack.c:491:7:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  if (read(fd, &hdr, sizeof(hdr)) < (int) sizeof(hdr))
data/pstack-1.3.1/pstack.c:567:40:  [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).
  for (nr = 0; bytes > sizeof(long) && strlen(dp) == nr;
data/pstack-1.3.1/pstack.c:719:14:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
