Summary
jetty security update
Details

Jetty is a 100% Java HTTP Server and Servlet Container. This means that you do not need to configure and run a separate web server (like Apache) in order\ to use Java, servlets and JSPs to generate dynamic content. Jetty is a fully\ featured web server for static and dynamic content. Unlike separate\ server/container solutions, this means that your web server and web\ application run in the same process, without interconnection overheads\ and complications. Furthermore, as a pure java component, Jetty can be simply\ included in your application for demonstration, distribution or deployment.\ Jetty is available on all Java supported platforms. \ %global extdesc \ \ This package contains

Security Fix(es):

For Eclipse Jetty versions <= 9.4.40, <= 10.0.2, <= 11.0.2, it is possible for requests to the ConcatServlet with a doubly encoded path to access protected resources within the WEB-INF directory. For example a request to /concat?/%2557EB-INF/web.xml can retrieve the web.xml file. This can reveal sensitive information regarding the implementation of a web application.(CVE-2021-28169)
