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

Summary SixLabors.ImageSharp can terminate a process when an application decodes an attacker-supplied 32-bit floating-point TIFF as Image and applies HistogramEqualization. An IEEE positive-infinity TIFF sample reaches a non-finite or otherwise out-of-range HalfVector4 component, depending on the...

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

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write through the HistogramEqualization process. An attacker can cause the application to terminate unexpectedly by supplying a specially crafted 32-bit floating-point TIFF image with non-finite values, which leads to an...

CVE-2026-106113

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 and applying HistogramEqualization can produce a non-finite or out-of-range luminance in ColorNumerics.GetBT709Luminance. GrayscaleLevelsRowOperation.Invoke uses the...

CVE-2026-106113

The ImageSharp 2D graphics library (versions 2.0.0 through 4.1.2 ) is vulnerable to an out-of-bounds access during the decoding of an attacker-supplied 32-bit floating-point TIFF as Image . When HistogramEqualization is applied, ColorNumerics.GetBT709Luminance can produce non-finite or out-of-ran...
