This allows remote attackers to generate an extremely high volume of logs, constituting a DoS attack. This DoS is compounded by the fact that the logging subsystem is synchronous.</p> <p>### Affected versions</p> <p>All versions of Tornado prior to 6.5 are affected. The vulnerable parser is enabled by default.</p> <p>### Solution</p> <p>Upgrade to Tornado version 6.5. In the meantime, risk can be mitigated by blocking `Content-Type: multipart/form-data` in a proxy.</p> <p><strong>Affected:</strong> PyPI: tornado</p> <p>### Summary</p> <p>When Tornado&#39;s ``multipart/form-data`` parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data.
