Jenkins is an open source automation server which enables developers around the world to reliably build, test, and deploy their software. The following releases contain fixes for security vulnerabilities: * Jenkins 2.263 * Jenkins LTS 2.361.1 Summaries of the vulnerabilities are below. More details, severity, and attribution can be found here: https://www.jenkins.io/security/advisory/2022-09-09/ We provide advance notification for security updates on this mailing list: https://groups.google.com/d/forum/jenkinsci-advisories If you discover security vulnerabilities in Jenkins, please report them as described here: https://www.jenkins.io/security/#reporting-vulnerabilities --- SECURITY-2868 / CVE-2022-2048 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 LTS 2.346.3 and earlier, 2.362 and earlier bundle versions of Jetty affected by the security vulnerability CVE-2022-2048. This vulnerability allows unauthenticated attackers to make the Jenkins UI unresponsive by exploiting Jetty's handling of invalid HTTP/2 requests, causing a denial of service. NOTE: 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.
