CVE-2020-25666

CVE-2020-25666 is a vulnerability in ImageMagick where four instances in HistogramCompare() (MagickCore/histogram.c) allow integer overflow during simple math calculations on RGB values and the color count. The patch switches calculations from int to ssize_t, addressing the overflow. Affected pro...

CVE-2020-25675

CVE-2020-25675 : ImageMagick’s CropImage() and CropImageToTiles() perform rounding on unconstrained pixel offsets, causing undefined behavior via integer overflow/out-of-range values when processing untrusted input. The upstream patch constrains pixel offsets to prevent these issues. Affected: Im...

CVE-2020-25666

There are 4 places in HistogramCompare in MagickCore/histogram.c where an integer overflow is possible during simple math calculations. This occurs in the rgb values and count value for a color. The patch uses casts to ssizet type for these calculations, instead of int. This flaw could impact...

CVE-2020-25676

In CatromWeights, MeshInterpolate, InterpolatePixelChannel, InterpolatePixelChannels, and InterpolatePixelInfo, which are all functions in /MagickCore/pixel.c, there were multiple unconstrained pixel offset calculations which were being used with the floor function. These calculations produced...

CVE-2020-25676

CVE-2020-25676 concerns ImageMagick. Multiple unconstrained pixel offset calculations in CatromWeights(), MeshInterpolate(), InterpolatePixelChannel(), InterpolatePixelChannels(), and InterpolatePixelInfo() (in MagickCore/pixel.c) were evaluated with floor(), producing undefined behavior via out-...

CVE-2020-27751

ImageMagick vulnerability CVE-2020-27751 affects MagickCore/quantum-export.c. Processing a crafted file can trigger undefined behavior: values outside the range of unsigned long long and a shift exponent too large for 64-bit, with the likely impact on availability. Affected are ImageMagick versio...

CVE-2020-27754

ImageMagick vulnerability CVE-2020-27754 stems from overflow-prone calls to PixelPacketIntensity() in IntensityCompare() within magick/quantize.c. A crafted input could return overflowed pixel intensities to callers; the patch fixes this by introducing ConstrainPixelIntensity() to clamp values wi...

CVE-2020-27754

In IntensityCompare of /magick/quantize.c, there are calls to PixelPacketIntensity which could return overflowed values to the caller when ImageMagick processes a crafted input file. To mitigate this, the patch introduces and uses the ConstrainPixelIntensity function, which forces the pixel...

CVE-2020-25665

The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory in routine WritePALMImage because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. The patch adds 256 to bytesperrow in the call to AcquireQuantumMemory. This could cause...
