CVE-2026-112892

Pillow is a Python imaging library. From 4.1.0 until 13.0.0, Pillow's MSP RLE decoder can expand a small file into an unbounded in-memory buffer. The decoder writes run-length output to BytesIO without limiting expansion to the declared image size. An attacker can supply a crafted MSP image to an...

CVE-2026-112404

The Pillow Python imaging library (versions 8.1.0 through 13.0.0 ) contains an out-of-bounds read in the TiffDecode.c tile and RGBA decode paths. The vulnerability occurs because the library fails to verify that required input rows fit within the data produced by libtiff when certain tags like Ph...

CVE-2026-112404 Pillow: OOB read in TiffDecode.c tile and RGBA paths leaks heap memory into pixels

Pillow is a Python imaging library. From 8.1.0 until 13.0.0, Pillow's TIFF tile and RGBA decode paths can read beyond row data produced by libtiff. In decodeTile and the RGBA unpacker path, when Pillow and libtiff interpret duplicated PhotometricInterpretation or BitsPerSample tags differently,...

CVE-2026-112403

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's JPEG decoder can write a full-width scanline into a buffer sized for a requested draft scale. ImagingJpegDecode does not verify libjpeg's actual output width and component count after scaling is requested, and an 8-bit lossless SOF3 JP...

CVE-2026-112400

Pillow is a Python imaging library. From 9.2.0 until 13.0.0, Pillow can retain a rejected GIF frame size after a decompression-bomb exception. In GifImageFile.seek, a crafted GIF can leave rejected dimensions stored after Image.DecompressionBombError; if an application catches that exception and...

CVE-2026-112399

Pillow is a Python imaging library. From 8.1.0 until 13.0.0, Pillow can allocate an APNG disposal background at the full canvas size before applying the decompression-bomb check. A crafted APNG with a small first frame, a very large declared canvas, and background disposal or first-frame OPPREVIO...

CVE-2026-112399

The Pillow Python imaging library (versions 8.1.0 through 13.0.0 ) is vulnerable to a memory exhaustion Denial of Service (DoS) when processing APNG images. The root cause is that the library allocates memory for the full canvas size during Image.open() before performing the decompression-bomb ch...
