Pillow: Out-of-bounds access in _imagingmorph on a zero-width image

Summary A PPM or PGM file can declare a width of 0, which Pillow accepts, producing an image of size 0, N. Passing that image to ImageMorph.MorphOp.apply makes the native morphology code index a row buffer at outrowwidth - 1, which is outrow-1 when the width is 0. The process crashes. Details The...

DEBIAN-CVE-2026-112397

Pillow is a Python imaging library. Prior to 13.0.0, Pillow's ImageMorph.MorphOp.apply can access memory before a row buffer for a zero-width image. PPM and PGM input can create an image with width zero, and the native morphology routine indexes outrowwidth - 1 without rejecting that geometry. An...

CVE-2026-112397

The Pillow Python imaging library is vulnerable to an out-of-bounds access in the ImageMorph.MorphOp.apply() function. The root cause is that the native morphology routine indexes outrow[width - 1] without validating geometry, allowing PPM and PGM inputs with a width of zero to trigger an out-of-...
