Vulnerability	Vulnerable Version
M HTTP Request Smuggling io.netty:netty-codec-http2 is a HTTP2 sub package for the netty library, an event-driven asynchronous network application framework. Affected versions of this package are vulnerable to HTTP Request Smuggling in the translation from HTTP/2 to HTTP/1.x, specifically when handling both the `:authority` pseudo-header and a literal `host` header in a single HEADERS frame. An attacker can manipulate request routing by supplying differing values for these headers, resulting in two `Host` headers in the resulting request object. How to fix HTTP Request Smuggling? Upgrade `io.netty:netty-codec-http2` to version 4.1.136.Final, 4.2.16.Final or higher.	[,4.1.136.Final)[4.2.0.Final,4.2.16.Final)
H Allocation of Resources Without Limits or Throttling io.netty:netty-codec-http2 is a HTTP2 sub package for the netty library, an event-driven asynchronous network application framework. Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the `Http2Decompressor.decompress`. An attacker can exhaust direct memory and cause the JVM to crash by sending crafted HTTP/2 `DATA` frames to applications that have HTTP/2 content decompression enabled via `DelegatingDecompressorFrameListener`.
