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.

The remote Red Hat Enterprise Linux CoreOS 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:0777 advisory.

  - PKCE support is not implemented in accordance with the RFC for OAuth 2.0 for Native Apps. Without the use     of PKCE, the authorization code returned by an authorization server is not enough to guarantee that the     client that issued the initial authorization request is the one that will be authorized. An attacker is     able to obtain the authorization code using a malicious app on the client-side and use it to gain     authorization to the protected resource. This affects the package com.google.oauth-client:google-oauth-     client before 1.31.0. (CVE-2020-7692)

  - SnakeYaml's Constructor() class does not restrict types which can be instantiated during deserialization.
    Deserializing yaml content provided by an attacker can lead to remote code execution. We recommend using     SnakeYaml's SafeConsturctor when parsing untrusted content to restrict deserialization. We recommend     upgrading to version 2.0 and beyond. (CVE-2022-1471)
