WritePALMImage() in /coders/palm.c used size_t casts in several areas of a calculation which could lead to values outside the range of representable type `unsigned long` undefined behavior when a crafted input file was processed by ImageMagick. The patch casts to `ssize_t` instead to avoid this issue. Red Hat Product Security marked the Severity as Low 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 ImageMagick 7.0.9-0. La función WritePALMImage() en el archivo /coders/palm.c usó conversiones size_t en varias áreas de un cálculo que podría conllevar a valores fuera del rango de comportamiento indefinido de tipo representable "unsigned long" cuando un archivo de entrada diseñado era procesado por ImageMagick. • https://bugzilla.redhat.com/show_bug.cgi?id=1894679 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 •

https://notcve.org/view.php?id=CVE-2020-27759
In IntensityCompare() of /MagickCore/quantize.c, a double value was being casted to int and returned, which in some cases caused a value outside the range of type `int` to be returned. The flaw could be triggered by a crafted input file under certain conditions when 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 7.0.8-68. En la función IntensityCompare() del archivo /MagickCore/quantize.c, un valor doble se convertía en int y era devuelto, lo que en algunos casos provocaba que se devolviera un valor fuera del rango de tipo "int". • https://bugzilla.redhat.com/show_bug.cgi?id=1894238 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 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 •

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 •
CVSS: 9.1EPSS: 0%CPEs: 7EXPL: 1CVE-2019-19949 – ImageMagick: heap-based buffer over-read in WritePNGImage in coders/png.c
https://notcve.org/view.php?id=CVE-2019-19949
In ImageMagick 7.0.8-43 Q16, there is a heap-based buffer over-read in the function WritePNGImage of coders/png.c, related to Magick_png_write_raw_profile and LocaleNCompare. En ImageMagick versión 7.0.8-43 Q16, se presenta una lectura excesiva de búfer en la región heap de la memoria en la función WritePNGImage del archivo coders/png.c, relacionada con Magick_png_write_raw_profile y LocaleNCompare. An out-of-bounds read was discovered in ImageMagick when writing PNG images. An attacker may abuse this flaw to trick a victim user into downloading a malicious image file and running it through ImageMagick, causing the application to crash. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00006.html https://github.com/ImageMagick/ImageMagick/issues/1561 https://lists.debian.org/debian-lts-announce/2019/12/msg00033.html https://lists.debian.org/debian-lts-announce/2020/08/msg00030.html https://usn.ubuntu.com/4549-1 https://www.debian.org/security/2020/dsa-4712 https://access.redhat.com/security/cve/CVE-2019-19949 https://bugzilla.redhat.com/show_bug.cgi?id=1792480 • CWE-125: Out-of-bounds Read •
