Debian DSA-5198-1 : jetty9 - security update

low Nessus Plugin ID 163753

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5198 advisory.

- In Eclipse Jetty versions 9.4.0 thru 9.4.46, and 10.0.0 thru 10.0.9, and 11.0.0 thru 11.0.9 versions, the parsing of the authority segment of an http scheme URI, the Jetty HttpURI class improperly detects an invalid input as a hostname. This can lead to failures in a Proxy scenario. (CVE-2022-2047)

- In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests. (CVE-2022-2048)

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

Solution

Upgrade the jetty9 packages.

For the stable distribution (bullseye), these problems have been fixed in version 9.4.39-3+deb11u1.
