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...

PYSEC-2026-3451

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...

DEBIAN-CVE-2026-59198

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...

CVE-2026-59205

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...

UBUNTU-CVE-2026-59203

Pillow is a Python imaging library. From 12.0.0 through 12.2.0, Pillow's EPS parser in PIL/EpsImagePlugin.py accepts a negative byte count in the %%BeginBinary directive, allowing a crafted EPS file to cause Image.open to seek backwards to the same directive and parse it repeatedly in an infinite...

CVE-2026-59200 Pillow: Decompression Bomb DoS via PdfParser.PdfStream.decode()

Pillow is a Python imaging library. From 5.1.0 until 12.3.0, PdfParser.PdfStream.decode in PIL/PdfParser.py calls zlib.decompress with bufsize set to the PDF stream Length field without bounding the decompressed output size, allowing a crafted FlateDecode PDF stream to exhaust memory from a small...

CVE-2026-59200

Summary: Pillow 5.1.0–12.3.0 contains a memory exhaustion vulnerability in PdfParser.PdfStream.decode() caused by calling zlib.decompress() with an unbounded output size (bufsize set to the PDF stream Length). This can allow a crafted FlateDecode PDF stream to exhaust memory on a small file. Affe...
