GHSA-JJ3Q-CWQJ-842R ImageSharp: CCITT fax decompression (T4/Modified Huffman): unbounded WriteBits overflows strip buffer — heap OOB write in SixLabors.ImageSharp

Summary When decoding a fax-compressed strip TIFF Compression=3 / Group 3 1D, or Compression=2 / Modified Huffman, the CCITT decompressors write decoded runs through BitWriterUtils.WriteBits/WriteBit/WriteZeroBit, which advance and write bits via Unsafe.Add with read-modify-write semantics —...

CVE-2026-101258

A vulnerability exists in Ghostscript where rendering a crafted PostScript or EPS document allows an attacker to bypass the -dSAFER sandbox. The root cause is a chain of memory corruption during document parsing combined with the runtime disabling of internal path access controls. This allows for...

CVE-2026-106118

The ImageSharp 2D graphics library (versions 3.0.0 through 4.1.1 ) is vulnerable to a heap out-of-bounds write during tiled TIFF decoding. The root cause is a mismatch where the destination buffer is allocated using TileWidth , but the T4, T6, and Modified Huffman decompressors are constructed us...

CVE-2026-106118 ImageSharp: Tiled fax TIFF: tile buffer sized by TileWidth but fax decompressor writes scanlines of ImageWidth — heap OOB write

ImageSharp is a 2D graphics library. From 3.0.0 until 4.1.1, tiled TIFF decoding allocates a destination buffer using TileWidth but TiffDecompressorsFactory.Create constructs T4, T6, and Modified Huffman decompressors using the full frame width. TiffDecoderCore.DecodeTilesChunky can therefore...

CVE-2026-106117 ImageSharp: CCITT fax decompression (T4/Modified Huffman): unbounded WriteBits overflows strip buffer — heap OOB write in SixLabors.ImageSharp

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...

CVE-2026-106117

The SixLabors.ImageSharp 2D graphics library (versions 3.0.0 through 4.1.1 ) is vulnerable to a heap out-of-bounds (OOB) write during the decoding of strip TIFF images using CCITT Group 3 or Modified Huffman compression. The root cause is that T4TiffCompression.WritePixelRun can accumulate oversi...
