GHSA-62P4-GMF7-7G93
Vulnerability from github – Published: 2026-07-20 21:08 – Updated: 2026-07-20 21:08Summary
When Pillow loads an uncompressed image whose tile uses the raw codec and a mode in Image._MAPMODES, and the image was opened from a filename, it memory-maps the file and builds the image's row pointers directly into the mapping via PyImaging_MapBuffer (src/map.c). The per-row spacing (stride) is taken from the tile arguments. map.c validates offset + ysize*stride <= buffer_len but never checks that stride is at least the natural row width xsize * pixelsize.
The McIdas AREA plugin (McIdasImagePlugin.py) derives stride, offset, xsize, and ysize directly from attacker-controlled 32-bit header words with no validation. By supplying a stride far smaller than the row width, an attacker makes each row pointer read xsize*pixelsize bytes that run past the mapped region. Accessing the pixels (e.g. Image.tobytes(),
getpixel, convert, save) then reads adjacent process memory (information disclosure) or faults (SIGBUS, denial of service).
Complete Code Trace
Step 1: McIdasImageFile._open - turns attacker header words into image size, file offset, and row stride with no validation.
# src/PIL/McIdasImagePlugin.py:41-70
s = self.fp.read(256)
if not _accept(s) or len(s) != 256: # _accept: prefix == b"\x00\x00\x00\x00\x00\x00\x00\x04"
raise SyntaxError(...)
self.area_descriptor = w = [0, *struct.unpack("!64i", s)] # w[1..64] = signed BE int32, ALL attacker-controlled
if w[11] == 1:
mode = rawmode = "L" # pixelsize 1, in _MAPMODES
elif w[11] == 2:
mode = rawmode = "I;16B" # pixelsize 2, in _MAPMODES
...
self._mode = mode
self._size = w[10], w[9] # (xsize, ysize) <-- attacker
offset = w[34] + w[15] # <-- attacker
stride = w[15] + w[10] * w[11] * w[14] # <-- attacker (set w[14]=0, w[15]=1 => stride=1)
self.tile = [
ImageFile._Tile("raw", (0, 0) + self.size, offset, (rawmode, stride, 1))
]
Step 2: ImageFile.load (mmap branch) - selects mmap and delegates to map_buffer.
# src/PIL/ImageFile.py:322-348
if use_mmap: # use_mmap = self.filename and len(self.tile) == 1
decoder_name, extents, offset, args = self.tile[0]
if (decoder_name == "raw" and isinstance(args, tuple) and len(args) >= 3
and args[0] == self.mode and args[0] in Image._MAPMODES):
if offset < 0: # only lower-bound guard on offset
raise ValueError("Tile offset cannot be negative")
with open(self.filename) as fp:
self.map = mmap.mmap(fp.fileno(), 0, access=mmap.ACCESS_READ)
if offset + self.size[1] * args[1] > self.map.size(): # == offset + ysize*stride; NO stride>=linesize check
raise OSError("buffer is not large enough")
self.im = Image.core.map_buffer(
self.map, self.size, decoder_name, offset, args # args = ("L", stride, 1)
)
Step 3: PyImaging_MapBuffer - builds row pointers at stride spacing into the mmap; validates everything except stride >= row width.
/* src/map.c:65-140 */
if (!PyArg_ParseTuple(args, "O(ii)sn(sii)",
&target, &xsize, &ysize, &codec, &offset, &mode_name, &stride, &ystep))
return NULL;
...
const ModeID mode = findModeID(mode_name); /* "L" */
if (stride <= 0) { /* attacker sets stride=1 (>0) -> NOT recomputed */
if (mode == IMAGING_MODE_L || mode == IMAGING_MODE_P) stride = xsize;
else if (isModeI16(mode)) stride = xsize * 2;
else stride = xsize * 4;
}
if (stride > 0 && ysize > PY_SSIZE_T_MAX / stride) {/* overflow guard only */
PyErr_SetString(PyExc_MemoryError, "Integer overflow in ysize"); return NULL;
}
size = (Py_ssize_t)ysize * stride; /* = 1*1 = 1 */
if (offset > PY_SSIZE_T_MAX - size) { ... }
...
if (offset + size > view.len) { /* 1 + 1 = 2 <= 256 -> PASSES */
PyErr_SetString(PyExc_ValueError, "buffer is not large enough");
PyBuffer_Release(&view); return NULL;
}
im = ImagingNewPrologueSubtype(mode, xsize, ysize, sizeof(ImagingBufferInstance));
/* im->linesize = xsize * pixelsize = 200000 (the REAL per-row read width) */
/* setup file pointers -- NO check that stride >= im->linesize */
if (ystep > 0) {
for (y = 0; y < ysize; y++) {
im->image[y] = (char *)view.buf + offset + y * stride; /* row points into mmap, spacing=1 */
}
} else { ... }
im->linesize (the number of bytes any consumer reads per row) is xsize * pixelsize = 200000, but the row pointers are only stride = 1 byte apart and the buffer is only offset + ysize*stride = 2 bytes "claimed". Nothing reconciles the two.
Step 4: pixel access (Image.tobytes() → raw encoder copy1) - reads linesize bytes from im->image[0], i.e. xsize bytes starting at view.buf + offset, running far past the mmap.
/* the raw "L" packer copies linesize (=xsize) bytes per row from im->image[y];
for row 0 that is view.buf+1 .. view.buf+1+200000, vs a 256-byte file. */
Chain Summary
SOURCE: McIdas AREA header words w[9],w[10],w[11],w[14],w[15],w[34] (Image.open on a path)
↓ McIdasImagePlugin._open: stride = w[15]+w[10]*w[11]*w[14] -> attacker sets stride=1 [McIdasImagePlugin.py:66]
↓ tile = ("raw", (0,0,xsize,1), offset, ("L", 1, 1)) [McIdasImagePlugin.py:68]
GADGET: ImageFile.load mmap branch -- only checks offset+ysize*stride<=len <- BUG: no stride>=linesize check [ImageFile.py:343]
↓ core.map_buffer(map, (xsize,1), "raw", offset, ("L",1,1)) [ImageFile.py:346]
SINK: PyImaging_MapBuffer: im->image[0] = view.buf + offset + 0*stride; linesize=xsize [map.c:134]
↓ Image.tobytes() raw "L" encoder reads linesize (=xsize) bytes from im->image[0]
IMPACT: reads xsize bytes from a tiny mmap -> OOB read of adjacent process memory (leak) or SIGBUS (DoS)
Proof of Concept
See attached poc.zip
Impact on a Parent Application
Any application that opens image files supplied by users from a path on disk (the common pattern: save upload to a temp file, then Image.open(path)), has the default plugin set (McIdas is registered by default), and subsequently reads/returns/re-encodes the decoded pixels (thumbnailing, format conversion, serving a preview), is exposed:
- Information disclosure (High): the decoded "image" contains bytes of the worker process's adjacent heap/mapped memory, which the app then serves or stores - potentially leaking secrets, credentials, or other users' data.
- Denial of service (High): a larger
xsizereliably crashes the worker with SIGBUS.
Suggested fix
Core fix in src/map.c (PyImaging_MapBuffer): reject offset < 0 and stride < im->linesize. Defense-in-depth in McIdasImagePlugin._open: reject offset < 0 or stride < xsize*pixelsize .

Vulnerability from github – Published: 2022-01-14 00:01 – Updated: 2022-01-15 00:02This vulnerability allows remote attackers to disclose sensitive information on affected installations of Bentley View 10.15.0.75. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of JT files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-15052.

Mitigation MIT-5
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Strategy: Language Selection
Use a language that provides appropriate memory abstractions.
CAPEC-540: Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
