Описание
Eclipse Jetty HTTP/2 client can force the server to allocate a humongous byte buffer that may lead to OoM and subsequently the JVM to exit
Original Report
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.
Impact
Remote peers can cause the JVM to crash or continuously report OOM.
Patches
12.0.17
Workarounds
No workarounds.
