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...

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-2020-27755

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-2020-27755

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

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-...

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-2020-27752

CVE-2020-27752 affects ImageMagick (MagickCore/quantum-private.h): processing a crafted image can trigger a heap buffer overflow, potentially impacting availability and possibly data integrity. Affected versions are prior to 7.0.9-0. Remediation not stated in the provided text; typical guidance i...

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-2020-25664

In WriteOnePNGImage of the PNG coder at coders/png.c, an improper call to AcquireVirtualMemory and memset allows for an out-of-bounds write later when PopShortPixel from MagickCore/quantum-private.h is called. The patch fixes the calls by adding 256 to rowbytes. An attacker who is able to supply ...

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...

CVE-2020-25663

A call to ConformPixelInfo in the SetImageAlphaChannel routine of /MagickCore/channel.c caused a subsequent heap-use-after-free or heap-buffer-overflow READ when GetPixelRed or GetPixelBlue was called. This could occur if an attacker is able to submit a malicious image file to be processed by...

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...
