CVE-2023-44487

TITLE

Debian Security Advisory 5540-1

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 HTTP/2 protocol implementation did not sufficiently verify if HPACK header values exceed their size limit. The following data is constructed from data provided by Red Hat's json file at: https://access.redhat.com/security/data/csaf/v2/advisories/2023/rhsa-2023_5896.json Red Hat officially shut down their mailing list notifications October 10, 2023. Due to this, Packet Storm has recreated the below data as a reference point to raise awareness. It must be noted that due to an inability to easily track revision updates without crawling Red Hat's archive, these advisories are single notifications and we strongly suggest that you visit the Red Hat provided links to ensure you have the latest information available if the subject matter listed pertains to your environment. - Packet Storm Staff ==================================================================== Red Hat Security Advisory Synopsis: Important: OpenShift Container Platform 4.12.40 bug fix and security update Advisory ID: RHSA-2023:5896-01 Product: Red Hat OpenShift Enterprise Advisory URL: https://access.redhat.com/errata/RHSA-2023:5896 Issue date: 2023-10-25 Revision: 01 CVE Names: CVE-2023-44487 ==================================================================== Summary: Red Hat OpenShift Container Platform release 4.12.40 is now available with updates to packages and images that fix several bugs and add enhancements.

CVE-2023-28709 Denial of Service. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur. 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 stable distribution (bookworm), these problems have been fixed in version 10.1.6-1+deb12u1. We recommend that you upgrade your tomcat10 packages.
