Description

Pillow is a Python imaging library. From 5.2.0 until 12.3.0, Pillow&#39;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.
