CVE-2026-112395: Pillow Tiled-TIFF Decoder Out-of-Bounds Read Vulnerability

Short explanation

The tiled-TIFF decoder in Pillow from version 8.2.0 until 13.0.0 can read past the tile buffer. This can expose adjacent heap data or crash the process.

Why does it matter?

Processing a crafted TIFF file can expose sensitive heap data or lead to application denial of service.

What should be done?

  • Update to version 13.0.0 or later
  • Follow vendor security advisories

Show the technical text from the sources

Pillow is a Python imaging library. From 8.2.0 until 13.0.0, Pillow's tiled-TIFF decoder can read past the tile buffer while copying four-byte pixels. In _decodeTile, libtiff can return a tile allocation smaller than the required row stride multiplied by the tile length, and Pillow's stride-and-copy loop walks beyond that allocation. An attacker can supply a crafted tiled TIFF to an application that loads it. This can expose adjacent heap data in pixels or crash the process. This issue is fixed in version 13.0.0.
