CVE-2017-14158
Scrapy denial of service vulnerability
Reported by mitre · Published September 5, 2017
scrapy is fixed in 2.15.0 and 2.14.1 (PyPI)
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.

Upgrade to a fixed version or later. Language registries are listed first, then Linux distributions, then vendor products.
