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.

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. This flaw affects ImageMagick versions prior to 7.0.8-68. • https://bugzilla.redhat.com/show_bug.cgi?id=1891606 https://lists.debian.org/debian-lts-announce/2021/01/msg00010.html https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •

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 •
