Denial of service binding form from JSON in Play Framework

Play Framework is a web framework for Java and Scala. A denial of service vulnerability has been discovered in verions 2.8.3 through 2.8.15 of Play's forms library, in both the Scala and Java APIs. This can occur when using either the `Form#bindFromRequest` method on a JSON request body or the `Form#bind` method directly on a JSON value. If the JSON data being bound to the form contains a deeply-nested JSON object or array, the form binding implementation may consume all available heap space and cause an `OutOfMemoryError`. If executing on the default dispatcher and `akka.jvm-exit-on-fatal-error` is enabled—as it is by default—then this can crash the application process. `Form.bindFromRequest` is vulnerable when using any body parser that produces a type of `AnyContent` or `JsValue` in Scala, or one that can produce a `JsonNode` in Java. This includes Play's default body parser. This vulnerability been patched in version 2.8.16. There is now a global limit on the depth of a JSON object that can be parsed, which can be configured by the user if necessary. As a workaround, applications that do not need to parse a request body of type `application/json` can switch from the default body parser to another body parser that supports only the specific type of body they expect.

Lightbend Play Framework 资源管理错误漏洞

Lightbend Play Framework是美国Lightbend公司的一款使用Scala语言编写的Web应用程序框架。 Lightbend Play Framework 2.8.3 版本到 2.8.15 版本存在资源管理错误漏洞，该漏洞源于在 JSON 请求正文上使用 Form#bindFromRequest 方法或直接在 JSON 值上使用 Form#bind 方法时，会导致拒绝服务。
