BIT-PILLOW-2026-112403 Pillow: Heap buffer overflow in ImagingJpegDecode

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...

Pillow Heap Buffer Overflow DoS

The vulnerability in the ImagingJpegDecode function of the Pillow JPEG decoder library is related to buffer overflow in memory. Exploitation of this vulnerability may allow a remote attacker to cause a denial of service or execute arbitrary code...

PT-2026-123470

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's FlashPix JPEG-tile decoder can write decoded scanlines beyond the allocated tile buffer. FlashPix FPX JPEG decoding selects raw mode LA with two bytes per pixel, while an unrecognized JPEG mode can be decoded as JCS UNKNOWN with four...

GHSA-8G5G-8VMR-9782 Pillow: Heap buffer overflow in ImagingJpegDecode

Summary JpegImageFile.draft — which Image.thumbnail calls automatically — requests 1/2, 1/4 or 1/8 scaled JPEG output and shrinks self.size and the tile extents to match, so setimage allocates a single-row decode buffer of ceilW/s samples. ImagingJpegDecode sets cinfo.scalenum/scaledenom, calls...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow via ImagingJpegDecode in src/libImaging/JpegDecode.c when processing a JPEG file whose header declares scanlines wider or with more components than the tile extents used to size the scanline buffer. Because th...

CVE-2026-112403

The Pillow Python imaging library contains a heap buffer overflow in the ImagingJpegDecode component affecting versions prior to 13.0.0 . The root cause is that the decoder fails to verify libjpeg 's actual output width and component count after a draft scale is requested. Specifically, an 8-bit ...
