Affected: Maven: org.eclipse.jetty:jetty-server

### Impact Remote DOS attack can cause out of memory

### Description There exists a security vulnerability in Jetty's `ThreadLimitHandler.getRemote()` which can be exploited by unauthorized users to cause remote denial-of-service (DoS) attack. By repeatedly sending crafted requests, attackers can trigger OutofMemory errors and exhaust the server's memory.

### Affected Versions

* Jetty 12.0.0-12.0.8 (Supported) * Jetty 11.0.0-11.0.23 (EOL) * Jetty 10.0.0-10.0.23 (EOL) * Jetty 9.3.12-9.4.55 (EOL)

### Patched Versions

* Jetty 12.0.9 * Jetty 11.0.24 * Jetty 10.0.24 * Jetty 9.4.56

### Workarounds

Do not use `ThreadLimitHandler`. Consider use of `QoSHandler` instead to artificially limit resource utilization.
