Pillow: MSP RLE decoder expands a tiny file into unbounded memory

Summary The MSP RLE decoder expands run-length data into an in-memory buffer with no cap tied to the declared image size. A small file that passes the pixel-count check can force hundreds of megabytes or more of allocation when the application loads pixels. Details The MSP decoder writes each run...
