In WriteOnePNGImage() of the PNG coder at coders/png.c, an improper call to AcquireVirtualMemory() and memset() allows for an out-of-bounds write later when PopShortPixel() from MagickCore/quantum-private.h is called. The patch fixes the calls by adding 256 to rowbytes. An attacker who is able to supply a specially crafted image could affect availability with a low impact to data integrity. This flaw affects ImageMagick versions prior to 6.9.10-68 and 7.0.8-68. En la función WriteOnePNGImage() del codificador PNG en el archivo coders/png.c, una llamada inapropiada a las funciones AcquireVirtualMemory() y memset() permite una escritura fuera de límites más tarde cuando se llama a la función PopShortPixel() del archivo MagickCore/quantum-private.h . • https://bugzilla.redhat.com/show_bug.cgi?id=1891605 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z3J6D7POCQYQKNVRDYLTTPM5SQC3WVTR • CWE-122: Heap-based Buffer Overflow •

A call to ConformPixelInfo() in the SetImageAlphaChannel() routine of /MagickCore/channel.c caused a subsequent heap-use-after-free or heap-buffer-overflow READ when GetPixelRed() or GetPixelBlue() was called. This could occur if an attacker is able to submit a malicious image file to be processed by ImageMagick and could lead to denial of service. It likely would not lead to anything further because the memory is used as pixel data and not e.g. a function pointer. This flaw affects ImageMagick versions prior to 7.0.9-0. Una llamada a la función ConformPixelInfo() en la rutina SetImageAlphaChannel() del archivo /MagickCore/channel.c, causó una LECTURA de uso de la memoria previamente liberada de la pila o desbordamiento del búfer de la pila, cuando se llamó a las funciones GetPixelRed() o GetPixelBlue(). • https://bugzilla.redhat.com/show_bug.cgi?id=1891601 https://github.com/ImageMagick/ImageMagick/issues/1723 https://github.com/ImageMagick/ImageMagick/issues/1723#issuecomment-718275153 • CWE-416: Use After Free •

A floating point math calculation in ScaleAnyToQuantum() of /MagickCore/quantum-private.h could lead to undefined behavior in the form of a value outside the range of type unsigned long long. The flaw could be triggered by a crafted input file under certain conditions when it is processed by ImageMagick. Red Hat Product Security marked this 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 7.0.8-68. Un cálculo matemático de punto flotante en la función ScaleAnyToQuantum() del archivo /MagickCore/quantum-private.h, podría conducir a un comportamiento indefinido en forma de un valor fuera del rango de tipo unsigned long long. • https://bugzilla.redhat.com/show_bug.cgi?id=1894234 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/txt.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`. 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 7.0.8-68. Se encontró uno fallo en ImageMagick en el archivo coders/txt.c. • https://bugzilla.redhat.com/show_bug.cgi?id=1894236 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 •
