Several vulnerabilities have been discovered in netty, a Java NIO client/server socket framework.

CVE-2019-20444

HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an 'invalid fold.'

CVE-2019-20445

HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header.

CVE-2020-7238

Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header. This issue exists because of an incomplete fix for CVE-2019-16869.

CVE-2020-11612

The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.

For Debian 9 stretch, these problems have been fixed in version 1:4.1.7-2+deb9u2.

We recommend that you upgrade your netty packages.

Several vulnerabilities were discovered in Netty, a Java NIO client/server socket framework :

CVE-2014-0193

WebSocket08FrameDecoder allows remote attackers to cause a denial of service (memory consumption) via a TextWebSocketFrame followed by a long stream of ContinuationWebSocketFrames.

CVE-2014-3488

The SslHandler allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via a crafted SSLv2Hello message.

CVE-2019-16869

Netty mishandles whitespace before the colon in HTTP headers (such as a 'Transfer-Encoding : chunked' line), which leads to HTTP request smuggling.

CVE-2019-20444

HttpObjectDecoder.java allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an 'invalid fold.'

CVE-2019-20445

HttpObjectDecoder.java allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header.

CVE-2020-7238

Netty allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line) and a later Content-Length header.

For Debian 8 'Jessie', these problems have been fixed in version 3.9.0.Final-1+deb8u1.

We recommend that you upgrade your netty-3.9 packages.
