How to fix?

Upgrade Debian:13 jetty9 to version 9.2.25-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream jetty9 package and not the jetty9 package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

In Eclipse Jetty, versions 9.2.x and older, 9.3.x (all configurations), and 9.4.x (non-default configuration with RFC2616 compliance enabled), transfer-encoding chunks are handled poorly. The chunk length parsing was vulnerable to an integer overflow. Thus a large chunk size could be interpreted as a smaller chunk size and content sent as chunk body could be interpreted as a pipelined request. If Jetty was deployed behind an intermediary that imposed some authorization and that intermediary allowed arbitrarily large chunks to be passed on unchanged, then this flaw could be used to bypass the authorization imposed by the intermediary as the fake pipelined request would not be interpreted by the intermediary as a request.
