CVE-2026-59198

CVE-2026-59198 · Pillow TGA RLE encoder can serialize up to ~57 KB of adjacent heap data into generated images

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow's TGA RLE encoder reads past its packed row buffer when saving a mode 1 image with TGA RLE compression, allowing adjacent process heap bytes to be copied into the generated TGA file. This issue is fixed in version 12.3.0.
