CVE-2019-9518

TITLE

HTTP/2 implementations do not robustly handle abnormal traffic and resource exhaustion

DESCRIPTION

Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU. Multiple HTTP/2 implementations are vulnerable to a variety of denial-of-service (DoS) attacks. HTTP/2 is the second version of the hypertext transfer protocol, which is mainly used to ensure the communication between the client and the server. A resource management error vulnerability exists in HTTP/2. An attacker could exploit this vulnerability to cause a denial of service. Description: Red Hat Decision Manager is an open source decision management platform that combines business rules management, complex event processing, Decision Model & Notation (DMN) execution, and Business Optimizer for solving planning problems. It automates business decisions and makes that logic available to the entire business. It is recommended to halt the server by stopping the JBoss Application Server process before installing this update; after installing the update, restart the server by starting the JBoss Application Server process. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat Data Grid 7.3.3 security update Advisory ID: RHSA-2020:0727-01 Product: Red Hat JBoss Data Grid Advisory URL: https://access.redhat.com/errata/RHSA-2020:0727 Issue date: 2020-03-05 CVE Names: CVE-2018-14335 CVE-2019-3805 CVE-2019-3888 CVE-2019-9512 CVE-2019-9514 CVE-2019-9515 CVE-2019-9518 CVE-2019-10173 CVE-2019-10174 CVE-2019-10184 CVE-2019-10212 CVE-2019-14379 ==================================================================== 1.
