Netty before 4.1.42.Final mishandles whitespace before the colon in HTTP headers (such as a "Transfer-Encoding : chunked" line), which leads to HTTP request smuggling.

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4600-1 advisory.

  - Netty before 4.1.42.Final mishandles whitespace before the colon in HTTP headers (such as a Transfer-     Encoding : chunked line), which leads to HTTP request smuggling. (CVE-2019-16869)

  - 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-2019-20444)

  - 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-2019-20445)

  - 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-2020-7238)

It was reported that Netty, a Java NIO client/server framework, is prone to a HTTP request smuggling vulnerability due to mishandling whitespace before the colon in HTTP headers.

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

For Debian 8 'Jessie', this problem has been fixed in version 1:3.2.6.Final-2+deb8u1.

We recommend that you upgrade your netty packages.
