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...
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-2020-25664
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 ...
Design/Logic Flaw
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 ...
Integer overflow
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-2020-25663
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
CVE-2020-25667 affects ImageMagick versions prior to 7.0.9-0. The vulnerability arises in TIFFGetProfiles() in /coders/tiff.c, where a misused strstr() can cause a large out-of-bounds read while locating the string dc:format="image/dng" in a profile, provided a crafted input file is processed. Th...

CVE-2020-25664
CVE-2020-25664 affects ImageMagick older than 6.9.10-68 and 7.0.8-68. In WriteOnePNGImage() of the PNG coder, an improper use of AcquireVirtualMemory() and memset() can lead to an out-of-bounds write after PopShortPixel() is invoked; the fix is to add 256 to rowbytes. An attacker with the ability...
