    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. TiffDecoderCo…

    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.…

    ImageSharp: TIFF CCITT T6 encoder writes beyond an undersized output buffer

    ImageSharp is a 2D graphics library. From 2.1.0 until 4.1.2, the TIFF CCITT Group 4 encoder allocates Width times rowsPerStrip bytes even though T6BitCompressor.CompressStrip can emit encoded row data and two 12-bit end-of-facsimile-block codes beyond that ca…

    ImageSharp: HistogramEqualization uses an unvalidated luminance as an unchecked histogram index

    ImageSharp is a 2D graphics library. From 2.0.0 until 4.1.2, decoding an attacker-supplied 32-bit floating-point TIFF as Image<HalfVector4> and applying HistogramEqualization can produce a non-finite or out-of-range luminance in ColorNumerics.GetBT709Luminanc…

    ImageSharp: ICC LUT16 output channel count can write beyond Vector4

    ImageSharp is a 2D graphics library. From 4.0.0 until 4.1.2, ICC LUT16 conversion accepts more than four output channels even though ClutCalculator.Calculate and LutEntryCalculator.CalculateLut store intermediate and output values in Vector4. When DecoderOpti…

    ImageSharp: TIFF CCITT T4 encoder can write past its compressed output buffer

    ImageSharp is a 2D graphics library. From 2.0.0 until 4.1.2, the TIFF CCITT Group 3 encoder allocates an undersized compressed-data buffer for narrow 1-bit images. TiffCcittCompressor.Initialize does not reserve enough space for the row data and T4 end-of-lin…

    Out-of-bounds Write in SixLabors ImageSharp

    ImageSharp is a 2D graphics API. An Out-of-bounds Write vulnerability has been found in the ImageSharp gif decoder, allowing attackers to cause a crash using a specially crafted gif. This can potentially lead to denial of service. The problem has been patched…

    Use After Free in SixLabors.ImageSharp

    ImageSharp is a managed, cross-platform, 2D graphics library. A heap-use-after-free flaw was found in ImageSharp's InitializeImage() function of PngDecoderCore.cs file. This vulnerability is triggered when an attacker passes a specially crafted PNG image file…
