Debian DLA-2991-1 : twisted - LTS security update

high Nessus Plugin ID 160979

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2991 advisory.

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. For the detailed security status of twisted please refer to its security tracker page at: https://security-tracker.debian.org/tracker/twisted Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at:

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the twisted packages.

For Debian 9 stretch, this problem has been fixed in version 16.6.0-2+deb9u3.
