CVE-2019-9511

TITLE

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

DESCRIPTION

Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. 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. The following advisory data is extracted from: https://access.redhat.com/security/data/csaf/v2/advisories/2024/rhsa-2024_5856.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.
