Pillow: Heap buffer overflow in FlashPix (FPX) JPEG decoding leads to code execution

Credits Researcher: Alex Bouffard [email protected] Summary A heap buffer overflow in Pillow's FlashPix FPX JPEG-tile decoder lets an attacker achieve arbitrary code execution by getting an application to open a single crafted file with Image.open. The file is recognized by content the OLE2...

CVE-2026-112398 Pillow: Heap buffer overflow in FlashPix (FPX) JPEG decoding leads to code execution

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 JCSUNKNOWN with four...

CVE-2026-112398

The Pillow Python imaging library contains a heap buffer overflow in the FlashPix (FPX) JPEG-tile decoder prior to version 13.0.0 . The vulnerability occurs because the ImagingJpegDecode function can be tricked into writing four-component scanlines into a two-byte tile buffer when processing cert...
