Descriptions
HTTP/2 denial of service vulnerabilities in bundled Jetty
SECURITY-3291 / CVE-2023-36478, CVE-2023-44487
Severity (CVSS): High
Description:

Jenkins bundles Winstone-Jetty, a wrapper around Jetty, to act as HTTP and servlet server when started using java -jar jenkins.war. This is how Jenkins is run when using any of the installers or packages, but not when run using servlet containers such as Tomcat.

Jenkins 2.427 and earlier, LTS 2.414.2 and earlier bundles versions of Jetty affected by the security vulnerabilities CVE-2023-36478 and CVE-2023-44487. These vulnerabilities allow unauthenticated attackers to cause a denial of service.
	This only affects instances that enable HTTP/2, typically using the --http2Port argument to java -jar jenkins.war or corresponding options in service configuration files. It is disabled by default in all native installers and the Docker images provided by the Jenkins project.

Jenkins 2.428, LTS 2.414.3 updates the bundled Jetty to version 10.0.17, which is unaffected by these issues.

Administrators unable to update to these releases of Jenkins (or newer) are advised to disable HTTP/2.

Just updated to 2.414.3 from the previous ebuild, works fine.
