https://notcve.org/view.php?id=CVE-2020-25666
08 Dec 2020 — 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 `ssize_t` type for these calculations, instead of `int`. This flaw could impact application reliability in the event that ImageMagick processes a crafted input file. This flaw affects ImageMagick versions prior to 7.0.9-0. • https://bugzilla.redhat.com/show_bug.cgi?id=1891612 • CWE-190: Integer Overflow or Wraparound •

CVE-2020-25675
https://notcve.org/view.php?id=CVE-2020-25675
08 Dec 2020 — 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 negative impact to application availability or other problems related to undefined behavior, in cases where ImageMagick processes untrusted input data. The upstream patch introduces functionality to constrain the pi... • https://bugzilla.redhat.com/show_bug.cgi?id=1891933 • CWE-190: Integer Overflow or Wraparound •

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-2020-25676 – Ubuntu Security Notice USN-7068-1
https://notcve.org/view.php?id=CVE-2020-25676
08 Dec 2020 — 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 undefined behavior in the form of out-of-range and integer overflows, as identified by UndefinedBehaviorSanitizer. These instances of undefined behavior could be triggered by an attacker who is able to sup... • https://bugzilla.redhat.com/show_bug.cgi?id=1891934 • CWE-190: Integer Overflow or Wraparound •

CVE-2020-27758
https://notcve.org/view.php?id=CVE-2020-27758
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`. 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 7.0.8-68.

CVE-2020-29599 – ImageMagick: Shell injection via PDF password could result in arbitrary code execution
https://notcve.org/view.php?id=CVE-2020-29599
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. ImageMagick versiones anteriores a 6.9.11-40 y versiones 7.x anteriores a 7.0.10-40 maneja inapropiadamente la opción -authenticate, que permite establecer una contraseña para archivos PDF protegidos con con... • https://github.com/coco0x0a/CVE-2020-29599 • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-91: XML Injection (aka Blind XPath Injection) •

CVE-2020-27771
https://notcve.org/view.php?id=CVE-2020-27771
04 Dec 2020 — In RestoreMSCWarning() of /coders/pdf.c there are several areas where calls to GetPixelIndex() could result in values outside the range of representable for the unsigned char type. The patch casts the return value of GetPixelIndex() to ssize_t type to avoid this bug. This undefined behavior could be triggered when ImageMagick processes a crafted pdf file. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impa... • https://bugzilla.redhat.com/show_bug.cgi?id=1898290 • CWE-190: Integer Overflow or Wraparound •
