In ImageMagick, there is an outside the range of representable values of type 'unsigned int' at MagickCore/quantum-private.h...

CVE-2020-27766

A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned long. This would most likely lead to an impact to application availability,...

CVE-2020-27764

In /MagickCore/statistic.c, there are several areas in ApplyEvaluateOperator where a sizet cast should have been a ssizet cast, which causes out-of-range values under some circumstances when a crafted input file is processed by ImageMagick...

CVE-2020-27762

A flaw was found in ImageMagick in coders/hdr.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char. This would most likely lead to an impact to application availability, but could...

CVE-2020-27758

A flaw was found in ImageMagick in coders/txt.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned long long. This would most likely lead to an impact to application availability, but...

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-2020-27754

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-2020-27752

A flaw was found in ImageMagick in MagickCore/quantum-private.h. This flaw allows an attacker who submits a crafted file processed by ImageMagick to trigger a heap buffer overflow. The highest threat from this vulnerability is to system availability and also a potential impact on data integrity...

CVE-2020-27750

A flaw was found in ImageMagick in MagickCore/colorspace-private.h and MagickCore/quantum.h. This flaw allows an attacker who submits a crafted file that is processed by ImageMagick to trigger undefined behavior in the form of values outside the range of types unsigned char and math division by...

CVE-2020-25675

A flaw was found in ImageMagick. Rounding calculations performed on unconstrained pixel offsets causes undefined behavior in the form of integer overflow and out-of-range values. Such issues could cause a negative impact to application availability or other problems related to undefined behavior,...

CVE-2020-25667

A flaw was found in 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...

CVE-2020-25663

A flaw was found during a call to ConformPixelInfo in the SetImageAlphaChannel routine of /MagickCore/channel.c. This issue causes a subsequent heap-use-after-free or heap-buffer-overflow READ when GetPixelRed or GetPixelBlue1 is called. This flaw can occur when an attacker can submit a malicious...

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-2020-27757

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-2020-27751

A flaw was found in ImageMagick in MagickCore/quantum-export.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned long long as well as a shift exponent that is too large for 64-bit type...

CVE-2020-25674

A flaw was found in ImageMagick. When the colormap has less than 256 valid values, the loop condition will continue to loop 256 times, attempting to pass invalid colormap data to the event logger, leading to an improper exit condition and an out-of-bounds read via heap-buffer-overflow. The highes...

CVE-2020-25676

A flaw was found ImageMagick. Multiple unconstrained pixel offset calculations produce undefined behavior in the form of out-of-range and integer overflows. These instances of undefined behavior could be triggered by an attacker who is able to supply a crafted input file. The highest threat from...

CVE-2020-25664

A flaw was found in ImageMagick. A specially crafted image could cause an out-of-bounds memory write leading to a crash. The highest threat from this vulnerability is to system availability...
