[Eclipse Jetty] HTTP/2 clients can force excessive memory allocation on server

The Eclipse Foundation is a Common Vulnerabilities and Exposures (CVE) Numbering Authority. This issue it used to request and track the progress of the assignment of a CVE for a vulnerability in the project code for an Eclipse open source project.

Basic information

Project name: Eclipse Jetty

Project id: rt/jetty

Request type: reservation

Versions affected: [12.0.0, 12.0.16]

Common Weakness Enumeration:

CWE-400

Common Vulnerability Scoring System: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Summary:

In Eclipse Jetty versions 12.0.0 to 12.0.16 included, an HTTP/2 client can specify a very large value for the HTTP/2 settings parameter SETTINGS_MAX_HEADER_LIST_SIZE. The Jetty HTTP/2 server does not perform validation on this setting, and tries to allocate a ByteBuffer of the specified capacity to encode HTTP responses, likely resulting in OutOfMemoryError being thrown, or even the JVM process exiting.
