Hi,

The following vulnerabilities were published for netty.

CVE-2019-20445[0]:
| 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[1]:
| 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.

Both appears to be fixed with the same fix upstream, as per [2].

If you fix the vulnerabilities please also make sure to include the
CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
