CVE-2020-27754 – Ubuntu Security Notice USN-7068-1
https://notcve.org/view.php?id=CVE-2020-27754
08 Dec 2020 — 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 intensities to be within the proper bounds in the event of an overflow. This flaw affects ImageMagick versions prior to 6.9.10-69 and 7.0.8-69. En la función IntensityCompare() del archivo /magick/quantize.c, se pr... • https://bugzilla.redhat.com/show_bug.cgi?id=1894231 • CWE-190: Integer Overflow or Wraparound •

CVE-2020-27751 – Ubuntu Security Notice USN-4988-1
https://notcve.org/view.php?id=CVE-2020-27751
08 Dec 2020 — 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. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. Se encontr... • https://bugzilla.redhat.com/show_bug.cgi?id=1891994 • CWE-190: Integer Overflow or Wraparound •

08 Dec 2020 — A flaw was found in ImageMagick in MagickCore/colorspace-private.h and MagickCore/quantum.h. 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` and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior.

CVE-2020-25674 – Ubuntu Security Notice USN-5335-1
https://notcve.org/view.php?id=CVE-2020-25674
08 Dec 2020 — 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, attempting to pass invalid colormap data to the event logger. The patch replaces the hardcoded 256 value with a call to MagickMin() to ensure the proper value is used. This could impact application availability when a ... • https://bugzilla.redhat.com/show_bug.cgi?id=1891928 • CWE-122: Heap-based Buffer Overflow •

08 Dec 2020 — 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`.

CVE-2020-27757
https://notcve.org/view.php?id=CVE-2020-27757
08 Dec 2020 — 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 ImageMagick. Red Hat Product Security marked this as Low because although it could potentially lead to an impact to application availability, no specific impact was shown in this case. This flaw affects ImageMagick vers... • https://bugzilla.redhat.com/show_bug.cgi?id=1894234 • CWE-190: Integer Overflow or Wraparound •

CVE-2020-27756 – Ubuntu Security Notice USN-4988-1
https://notcve.org/view.php?id=CVE-2020-27756
08 Dec 2020 — 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 multiplication in addition to the function `PerceptibleReciprocal()` in order to prevent such divide-by-zero conditions. This flaw affects ImageMagick versions prior to 7.0.9-0.

https://notcve.org/view.php?id=CVE-2020-25665
08 Dec 2020 — 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 bytes_per_row in the call to AcquireQuantumMemory(). This could cause impact to reliability.

CVE-2020-29599 – ImageMagick: Shell injection via PDF password could result in arbitrary code execution

07 Dec 2020 — ImageMagick before 6.9.11-40 and 7.x before 7.0.10-40 mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c.
