TITLE

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

DESCRIPTION

Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, 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. Red Hat A-MQ is a standards compliant messaging system that is tailored for use in mission critical applications. It includes bug fixes, which are documented in the patch notes accompanying the package on the download page. See the download link given in the references section below. The References section of this erratum contains a download link (you must log in to download the update). The purpose of this text-only errata is to inform you about the security issues fixed in this release.
