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`. How to fix Allocation of Resources Without Limits or Throttling? Upgrade `io.netty:netty-codec-http2` to version 4.1.136.Final, 4.2.16.Final or higher.	[4.1.0.Final,4.1.136.Final)[4.2.0.Final,4.2.16.Final)
M 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 handling of the `SETTINGS_MAX_HEADER_LIST_SIZE` setting, when acting as a server. An attacker can cause the server to trigger exceptions during response header writing, by sending artificially small header size limits that block other clients' requests. How to fix Allocation of Resources Without Limits or Throttling? Upgrade `io.netty:netty-codec-http2` to version 4.1.135.Final, 4.2.15.Final or higher.	[,4.1.135.Final)[4.2.0.Alpha1,4.2.15.Final)
M Missing Release of Memory after Effective Lifetime 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 Missing Release of Memory after Effective Lifetime in the `DelegatingDecompressorFrameListener` function. An attacker can cause memory exhaustion and potentially crash the JVM by sending specially crafted HTTP/2 frames that trigger a resource leak. How to fix Missing Release of Memory after Effective Lifetime? Upgrade `io.netty:netty-codec-http2` to version 4.1.135.Final, 4.2.15.Final or higher.	[,4.1.135.Final)[4.2.0.Alpha1,4.2.15.Final)
M 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 due to the lack of enforcement of the advertised `MAX_CONCURRENT_STREAMS` setting in HTTP/2 connections in `AbstractHttp2ConnectionHandlerBuilder`. An attacker can exhaust server resources by opening a large number of concurrent streams over a single TCP connection, potentially leading to service disruption. How to fix Allocation of Resources Without Limits or Throttling? Upgrade `io.netty:netty-codec-http2` to version 4.1.135.Final, 4.2.15.Final or higher.	[,4.1.135.Final)[4.2.0.Final,4.2.15.Final)
