Vulnerability Title
Undertow-core: undertow: denial of service via websocket permessage-deflate processing
来源: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in Undertow. A remote attacker could exploit this vulnerability by sending specially crafted WebSocket messages with permessage-deflate negotiated. This could lead to excessive memory consumption due to the PerMessageDeflateFunction.largerBuffer() method using exponential doubling, resulting in a Denial of Service (DoS) for the affected application.
