Package        : twisted
Version        : 16.6.0-2+deb9u3
CVE ID         : CVE-2022-24801
Debian Bug     : 1009030

The Twisted Web HTTP 1.1 server, located in the twisted.web.http module, parsed
several HTTP request constructs more leniently than permitted by RFC 7230. This
non-conformant parsing can lead to desync if requests pass through multiple
HTTP parsers, potentially resulting in HTTP request smuggling.

For Debian 9 stretch, this problem has been fixed in version

We recommend that you upgrade your twisted packages.

For the detailed security status of twisted please refer to
