Summary Pillow's TGA RLE encoder reads past its row buffer when saving a mode "1" image. Adjacent process heap bytes can be copied into the generated TGA file. The bug is reachable through the public save API: python im.saveout, format="TGA", compression="tga rle" Older affected Pillow versions u...

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

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...
