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-2020-27756

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...

Undefined Behavior

ImageMagick is vulnerable to undefined behavior in the form of out-of-range and integer overflows. An attacker may trigger the vulnerability by supplying a crafted input file to be processed by ImageMagick...

Undefined Behavior

ImageMagick is vulnerable to undefined behavior. The vulnerability exist when ImageMagick processed a crafted input file and use sizet in several calculations represented by type unsigned long...

Denial Of Service (DoS)

imagemagick is vulnerable to denial of service DoS. The vulnerability exists in GammaImage of /MagickCore/enhance.c, depending on the gamma value, it's possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick...

Value Overflow

ImageMagick is vulnerable to value overflow. An attacker can enter a craftd input file to PixelPacketIntensity which could return overflowed values...

CVE-2020-27770

Due to a missing check for 0 value of replaceextent, it is possible for offset p to overflow in SubstituteString, causing potential impact to application availability. This could be triggered by a crafted input file that is processed by ImageMagick. This flaw affects ImageMagick versions prior to...
