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...

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...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop via incorrect initialization of nframes and isanimated in TiffImagePlugin.TiffImageFile, where nframes was set inside open rather than init, allowing it to be overwritten by a MicImageFile subclass. An attacker can supply ...

CVE-2026-112390

Pillow is a Python imaging library. From 7.2.0 until 13.0.0, Pillow can enter an infinite loop while determining the frame count of a MIC image. MicImageFile inherits TIFF frame traversal, but MicImageFile.tell reports the OLE stream index and its seek resets TIFF frame state, so an embedded TIFF...

Pillow Resource Management Error Vulnerability

Pillow versions 7.2.0 to 13.0.0 contain a resource management vulnerability. This vulnerability arises from an infinite loop that may occur when determining the number of MIC image frames. MicImageFile inherits the frame traversal from TIFF, but MicImageFile.tell reports the OLE stream index, and...
