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. Apple SwiftNIO and Apache Traffic Server Used in HTTP/2 Contains a resource exhaustion vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. 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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: Red Hat JBoss Fuse/A-MQ 6.3 R14 security and bug fix update Advisory ID: RHSA-2019:4352-01 Product: Red Hat JBoss Fuse Advisory URL: https://access.redhat.com/errata/RHSA-2019:4352 Issue date: 2019-12-19 CVE Names: CVE-2019-0201 CVE-2019-9512 CVE-2019-9514 CVE-2019-9515 CVE-2019-9518 CVE-2019-10173 CVE-2019-12384 ==================================================================== 1.

Description: Red Hat Process Automation Manager is an open source business process management suite that combines process management and decision service management and enables business and IT users to create, manage, validate, and deploy process applications and decision services. 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. The fixes are too intrusive to backport to the version in the oldstable distribution (stretch). An upgrade to Debian stable (buster) is recommended instead. For the stable distribution (buster), these problems have been fixed in version 8.0.2+ds-1+deb10u1. We recommend that you upgrade your trafficserver packages.
