CVE-2019-9514

TITLE

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

DESCRIPTION

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. 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. it exists that Twisted incorrectly validated or sanitized certain URIs or HTTP methods. A remote attacker could use this issue to inject invalid characters and possibly perform header injection attacks. (CVE-2019-12387). -----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.

This advisory contains the ansible-operator, apb, containernetworking-plugins, golang-github-openshift-prometheus-alert-buffer, golang-github-prometheus-promu and openshift-eventrouter RPM packages for Red Hat OpenShift Container Platform 4.1.21. These packages have been rebuilt with an updated version of Go to address the below security issues. Solution: For OpenShift Container Platform 4.1 see the following documentation, which will be updated shortly for release 4.1.21, for important instructions on how to upgrade your cluster and fully apply this asynchronous errata update: https://docs.openshift.com/container-platform/4.1/release_notes/ocp-4-1-rel ease-notes.html 5. Our key and details on how to verify the signature are available from https://access.redhat.com/security/team/key/ 7. Description: The Container Network Interface (CNI) project consists of a specification and libraries for writing plug-ins for configuring network interfaces in Linux containers, along with a number of supported plug-ins. CNI concerns itself only with network connectivity of containers and removing allocated resources when the container is deleted. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 5. 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.
