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. En la función ParseMetaGeometry() del archivo MagickCore/geometry.c, los cálculos de altura y ancho de la imagen pueden conllevar a condiciones de división por cero que también conllevan a un comportamiento indefinido. • https://bugzilla.redhat.com/show_bug.cgi?id=1894233 https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html • CWE-369: Divide By Zero •

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 encontró un fallo en ImageMagick en el archivo MagickCore/quantum-export.c. • https://bugzilla.redhat.com/show_bug.cgi?id=1891994 https://lists.debian.org/debian-lts-announce/2021/06/msg00000.html https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html • CWE-190: Integer Overflow or Wraparound •

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 https://lists.debian.org/debian-lts-announce/2021/03/msg00030.html https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html • CWE-190: Integer Overflow or Wraparound •

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 supply a crafted input file to be processed by ImageMagick. These issues could impact application availability or potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0. • https://bugzilla.redhat.com/show_bug.cgi?id=1891934 https://lists.debian.org/debian-lts-announce/2021/03/msg00030.html https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html • CWE-190: Integer Overflow or Wraparound •

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 pixel offsets and prevent these issues. This flaw affects ImageMagick versions prior to 7.0.9-0. En las rutinas CropImage() y CropImageToTiles() del archivo MagickCore/transform.c, los cálculos de redondeo realizados en desplazamientos de píxeles sin restricciones provocaban un comportamiento indefinido en forma de desbordamiento de enteros y valores fuera de rango según lo informado por UndefinedBehaviorSanitizer. • https://bugzilla.redhat.com/show_bug.cgi?id=1891933 https://lists.debian.org/debian-lts-announce/2021/03/msg00030.html https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html • CWE-190: Integer Overflow or Wraparound •
