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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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.
