Descriptions

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. Dichos problemas podrían causar un impacto negativo en la disponibilidad de la aplicación u otros problemas relacionados con el comportamiento indefinido, en los casos en que ImageMagick procesa datos de entrada que no son confiables. El parche previo introduce una funcionalidad para limitar los desplazamientos de píxeles y evitar estos problemas. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0
