Pillow is a Python imaging library. From 11.0.0 until 13.0.0, multi-frame loaders can retain an ImagingCore allocation created for a narrow frame mode while a later frame of the same dimensions changes the logical mode and decoder tiles to wider RGB or CMYK data. ImageFile.load prepare reuses the...

Pillow multi-frame loaders can reuse stale native image storage after mode transitions

Summary Pillow multi-frame image loaders can retain native ImagingCore storage allocated for one frame while changing the Python-side image mode and decoder tiles for a later frame. If frame 0 allocates storage for a narrow mode such as L, and a later frame of the same dimensions switches to a...

Out-of-bounds Write

Overview Pillow is a PIL Python Imaging Library fork. Affected versions of this package are vulnerable to Out-of-bounds Write via the seek method in multiple multi-frame image format plugins DCX, JPEG, MIC, MPO, PSD, when an image's mode or size changes between frames during a seek operation. The...
