CVE-2020-27760
https://notcve.org/view.php?id=CVE-2020-27760
In `GammaImage()` of /MagickCore/enhance.c, depending on the `gamma` value, it's possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. The patch uses the `PerceptibleReciprocal()` to prevent the divide-by-zero from occurring. This flaw affects ImageMagick versions prior to ImageMagick 7.0.8-68. En la función "GammaImage()" del archivo /MagickCore/enhance.c, dependiendo del valor de "gamma", es posible activar una condición de división por cero cuando ImageMagick procesa un archivo de entrada diseñado. • https://bugzilla.redhat.com/show_bug.cgi?id=1894239 https://lists.debian.org/debian-lts-announce/2021/01/msg00010.html https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html • CWE-369: Divide By Zero •
CVE-2020-27762
https://notcve.org/view.php?id=CVE-2020-27762
A flaw was found in ImageMagick in coders/hdr.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 char`. 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 ImageMagick 7.0.8-68. Se encontró un fallo en ImageMagick en el archivo coders/hdr.c. • https://bugzilla.redhat.com/show_bug.cgi?id=1894680 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 •

A flaw was found in ImageMagick in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of 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-2020-27764
https://notcve.org/view.php?id=CVE-2020-27764
In /MagickCore/statistic.c, there are several areas in ApplyEvaluateOperator() where a size_t cast should have been a ssize_t cast, which causes out-of-range values under some circumstances when a crafted input file is processed by ImageMagick. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impact was shown in this case. This flaw affects ImageMagick versions prior to 6.9.10-69. En el archivo /MagickCore/statistic.c, presenta varias áreas en la función ApplyEvaluateOperator() donde una conversión size_t debería haber sido una conversión ssize_t, lo que causa valores fuera de rango bajo algunas circunstancias cuando ImageMagick procesa un archivo de entrada diseñado. Red Hat Product Security marcó esto como de gravedad baja porque, aunque podría generar un impacto en la disponibilidad de la aplicación, ningún impacto específico fue mostrado en este caso. • https://bugzilla.redhat.com/show_bug.cgi?id=1894683 https://github.com/ImageMagick/ImageMagick6/commit/3e21bc8a58b4ae38d24c7e283837cc279f35b6a5 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 •
