PYSEC-2026-3495 Pillow: Decompression Bomb DoS via PdfParser.PdfStream.decode()

Summary PdfParser.PdfStream.decode in Pillow's PdfParser.py calls zlib.decompress with the bufsize parameter set to the value of the PDF stream's Length field, without any upper bound on the actual decompressed output size. Python's zlib.decompress bufsize argument is an initial output buffer hin...

BIT-PILLOW-2026-59205 Pillow: Controlled heap out-of-bounds write in `ImageCmsTransform.apply()` via output mode mismatch

Pillow is a Python imaging library. Prior to 12.3.0, Pillow's ImageCms.ImageCmsTransform.applyim, imOut API can trigger controlled native heap corruption when the caller supplies an output image whose mode does not match the transform's declared output mode. This issue is fixed in version 12.3.0...

BIT-PILLOW-2026-59198 Pillow TGA RLE encoder can serialize up to ~57 KB of adjacent heap data into generated images

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0...

DEBIAN-CVE-2026-59197

Pillow is a Python imaging library. Prior to 12.3.0, Pillow's public rank-filter API can trigger a native heap out-of-bounds write when given a very large odd filter size because ImageFilter.RankFilter.filter calls image.expandsize // 2, size // 2 before rank-filter size validation and...

CVE-2026-59197 Pillow: Heap out-of-bounds write in Pillow `ImageFilter.RankFilter` via integer overflow in `ImagingExpand`

Pillow is a Python imaging library. Prior to 12.3.0, Pillow's public rank-filter API can trigger a native heap out-of-bounds write when given a very large odd filter size because ImageFilter.RankFilter.filter calls image.expandsize // 2, size // 2 before rank-filter size validation and...

DEBIAN-CVE-2026-59204

Pillow is a Python imaging library. From 8.2.0 through 12.2.0, src/libImaging/Jpeg2KDecode.c accumulates totalcomponentwidth across every tile in a JPEG2000 image instead of recomputing it per tile, allowing a crafted tiled JPEG2000 file to force substantially higher transient memory usage and...

DEBIAN-CVE-2026-59199

Pillow is a Python imaging library. Prior to 12.3.0, Pillow public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits in Image.paste, Image.crop, or Image.alphacomposite. This issue is fixed in version 12.3.0...
