Title

Undertow: outofmemoryerror in httpservletrequestimpl.getparameternames() can cause remote dos attacks

Summary

A flaw was found in Undertow. Servlets using a method that calls HttpServletRequestImpl.getParameterNames() can cause an OutOfMemoryError when the client sends a request with large parameter names. This issue can be exploited by an unauthorized user to cause a remote denial-of-service (DoS) attack.
