| Doc Text: |
A flaw was found in the `python` and `expat` components. Insufficient entropy in the hash-flooding protection mechanism of `xml.parsers.expat` and `xml.etree.ElementTree` allows a remote attacker to craft a malicious XML document. This crafted document can trigger a hash flooding attack, leading to a denial of service (DoS) condition.
