https://notcve.org/view.php?id=CVE-2020-27771
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 impact was demonstrated in this case. This flaw affects ImageMagick versions prior to 7.0.9-0. • https://bugzilla.redhat.com/show_bug.cgi?id=1898290 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/statistic.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`. 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 7.0.8-69.

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 •
