DLA-2991-1 twisted -- LTS security update

Date Reported:
10 May 2022
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 1009030.
In Mitre's CVE dictionary: CVE-2022-24801.
More information:

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 16.6.0-2+deb9u3.

We recommend that you upgrade your twisted packages.
