TITLE

Red Hat Security Advisory 2023-6048-01

DESCRIPTION

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. The updated image includes new features and bug fixes. It contains the following bug fixes and changes: * Previously, Red Hat OpenShift Container Platform customers using the downloaded manifest bundle with automatic upgrades enabled found that Sensor did not automatically upgrade, and failed with a `PRE_FLIGHT_CHECKS_FAILED` error. This issue has been fixed. (ROX-19955) * RHACS 4.2.2 includes a new default policy called \"Rapid Reset: Denial of Service Vulnerability in HTTP/2 Protocol\". This policy alerts on deployments with images containing components that are susceptible to a Denial of Service (DoS) vulnerability for HTTP/2 servers, based on CVE-2023-44487 and CVE-2023-39325. This policy applies to the build or deploy life cycle stage.

CVE-2023-24998 Denial of service. Tomcat uses a packaged renamed copy of Apache Commons FileUpload to provide the file upload functionality defined in the Jakarta Servlet specification. Apache Tomcat was, therefore, also vulnerable to the Commons FileUpload vulnerability CVE-2023-24998 as there was no limit to the number of request parts processed. This resulted in the possibility of an attacker triggering a DoS with a malicious upload or series of uploads. CVE-2023-41080 Open redirect. If the ROOT (default) web application is configured to use FORM authentication then it is possible that a specially crafted URL could be used to trigger a redirect to an URL of the attackers choice. CVE-2023-42795 Information Disclosure. When recycling various internal objects, including the request and the response, prior to re-use by the next request/response, an error could cause Tomcat to skip some parts of the recycling process leading to information leaking from the current request/response to the next. CVE-2023-44487 DoS caused by HTTP/2 frame overhead (Rapid Reset Attack) CVE-2023-45648 Request smuggling. Tomcat did not correctly parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a single request as multiple requests leading to the possibility of request smuggling when behind a reverse proxy. For the oldstable distribution (bullseye), these problems have been fixed in version 9.0.43-2~deb11u7. We recommend that you upgrade your tomcat9 packages.
