UBUNTU-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...

UBUNTU-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-2020-27756

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...

Input validation

There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values, which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact to application availability or cause a denial of service. It was originally reported tha...

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-2020-27752

A flaw was found in ImageMagick in MagickCore/quantum-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger a heap buffer overflow. This would most likely lead to an impact to application availability, but could potentially lead to an impact to data...

CVE-2020-25675

In the CropImage and CropImageToTiles routines of MagickCore/transform.c, rounding calculations performed on unconstrained pixel offsets was causing undefined behavior in the form of integer overflow and out-of-range values as reported by UndefinedBehaviorSanitizer. Such issues could cause a...

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-2020-27754

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 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...

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-2020-27755

CVE-2020-27755 affects ImageMagick. In SetImageExtent() (MagickCore/image.c), an incorrect image depth size is not reset when an invalid size is encountered, causing a memory leak. The patch fixes this by resetting the depth to a proper size before throwing, mitigating the leak. A crafted input f...

CVE-2020-27753

There are several memory leaks in the MIFF coder in /coders/miff.c due to improper image depth values, which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact to application availability or cause a denial of service. It was originally reported tha...

CVE-2020-27753

CVE-2020-27753 affects ImageMagick’s MIFF coder (/coders/miff.c). It describes memory leaks caused by improper image depth handling, triggered by crafted MIFF inputs. Patch fixes occur in the MIFF coder (not in AcquireMagickMemory itself) and the issue affects ImageMagick versions prior to 7.0.9-...
