ImageSharp: CCITT fax decompression T4/Modified Huffman: unbounded WriteBits overflows strip buffer — heap OOB write in SixLabors.ImageSharp...

CVE-2026-106117

ImageSharp is a 2D graphics library. From 3.0.0 until 4.1.1, decoding a strip TIFF using CCITT Group 3 or Modified Huffman compression can pass attacker-expanded runs to BitWriterUtils.WriteBits without first checking the current row width. T4TiffCompression.WritePixelRun can accumulate oversized...
