Transfer-Encoding whitespace (such as a [space]Transfer-Encoding:chunked line)
and a later Content-Length header. This issue exists because of an incomplete

JFI: I submitted requests to update our netty package to 4.1.14 which fixes this vulnerability, and Uyuni patches to adapt to the new version.

https://github.com/uyuni-project/uyuni/pull/1877

This fix will be part of the next SUSE Manager major version, 4.1, as well.
