Descriptions

Scrapy 1.4 allows remote attackers to cause a denial of service (memory consumption) via large files because arbitrarily many files are read into memory, which is especially problematic if the files are then individually written in a separate thread to a slow storage resource, as demonstrated by interaction between dataReceived (in core/downloader/handlers/http11.py) and S3FilesStore.

Scrapy 1.4 permite que atacantes remotos provoquen una denegación de servicio (consumo de memoria) utilizando archivos de gran tamaño, ya que se leen numerosos archivos en la memoria. Esto resulta especialmente problemático si los archivos se escriben posteriormente de manera individual en un hilo separado a un recurso de almacenamiento lento. Esto se ha demostrado con la interacción entre dataReceived (en core/downloader/handlers/http11.py) y S3FilesStore.
