Summary

Pillow, a widely used image processing library in Python, is affected by a buffer over-read vulnerability in the SGIRleDecode function. This issue arises when the library is tasked with decoding specially crafted SGI RLE image files, leading to mishandled offsets and length tables. As a result, the library may read beyond allocated memory boundaries, potentially exposing sensitive information or causing application crashes.
