UBUNTU-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...

UBUNTU-CVE-2020-27756

In ParseMetaGeometry of MagickCore/geometry.c, image height and width calculations can lead to divide-by-zero conditions which also lead to undefined behavior. This flaw can be triggered by a crafted input file processed by ImageMagick and could impact application availability. The patch uses...

CVE-2020-25674

WriteOnePNGImage from coders/png.c the PNG coder has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times,...

Code injection

in SetImageExtent of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because the code which checks for the proper image depth size does not reset the size in the event there is an invalid size. The patch resets the depth to a proper size before throwing an exception. Th...

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...

Design/Logic Flaw

A floating point math calculation in ScaleAnyToQuantum of /MagickCore/quantum-private.h could lead to undefined behavior in the form of a value outside the range of type unsigned long long. The flaw could be triggered by a crafted input file under certain conditions when it is processed by...

CVE-2020-27755

in SetImageExtent of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because the code which checks for the proper image depth size does not reset the size in the event there is an invalid size. The patch resets the depth to a proper size before throwing an exception. Th...

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-2020-25667

TIFFGetProfiles in /coders/tiff.c calls strstr which causes a large out-of-bounds read when it searches for "dc:format="image/dng" within profile due to improper string handling, when a crafted input file is provided to ImageMagick. The patch uses a StringInfo type instead of a raw C string to...

ImageMagick Studio ImageMagick 输入验证错误漏洞

ImageMagick is a suite of open source image processing software. The software can read, convert or write images in a variety of formats. ImageMagick suffers from a security vulnerability, which stems from IntensityCompare of /magick/quantize.c, where a call to PixelPacketIntensity returns an...
