CVE-2026-59198
MEDIUMPillow TGA RLE encoder can serialize up to ~57 KB of adjacent heap data into generated images
Title source: cnaDescription
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.
