pillow: Pillow: Heap buffer overflow in _tiffWriteProc when saving TIFF to BytesIO

A flaw was found in Pillow. When saving compressed Tagged Image File Format TIFF images into memory buffers rather than direct files, the library incorrectly calculates the required memory allocation. A remote attacker who supplies a crafted image for processing can trigger a heap-based buffer...

BIT-PILLOW-2026-112892 Pillow: MSP RLE decoder expands a tiny file into unbounded memory

Pillow is a Python imaging library. From 4.1.0 until 13.0.0, Pillow's MSP RLE decoder can expand a small file into an unbounded in-memory buffer. The decoder writes run-length output to BytesIO without limiting expansion to the declared image size. An attacker can supply a crafted MSP image to an...

BIT-PILLOW-2026-112393 Pillow: Heap buffer overflow in _tiffWriteProc when saving TIFF to BytesIO

Pillow is a Python imaging library. From 2.0.0 until 13.0.0, Pillow has a heap buffer overflow and stale-heap disclosure in tiffWriteProc when saving compressed TIFF data through libtiff to a target without a usable fileno, such as BytesIO. The callback sizes its allocation from the prior buffer...
