pillow: Pillow is a Python imaging library
CVE-2026-59200 is fixed in 11 products on 1 platform, first by python3-pil 9.0.1-1ubuntu0.6, released July 14, 2026. It is not reported as exploited. Patch Radar priority: High.
Pillow is a Python imaging library. From 5.1.0 until 12.3.0, PdfParser.PdfStream.decode() in PIL/PdfParser.py calls zlib.decompress() with bufsize set to the PDF stream Length field without bounding the decompressed output size, allowing a crafted FlateDecode PDF stream to exhaust memory from a small file. This issue is fixed in version 12.3.0.
