medium Nessus Plugin ID 170224

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

The remote openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2022:1315-1 advisory.

 - Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did miss to fix this one case.
 This was fixed as part of 4.1.61.Final. (CVE-2021-21409)

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

Solution

Update the affected netty, netty-javadoc and / or netty-poms packages.
