"Oleg Kalnichevski discovered that httpcomponents-client, a Java
library for building HTTP-aware applications, can misinterpret a
malformed authority component in request URIs passed to the library as
java.net.URI object and pick the wrong target host for request
execution.

For Debian 9 stretch, this problem has been fixed in version
4.5.2-2+deb9u1.

We recommend that you upgrade your httpcomponents-client packages.

For the detailed security status of httpcomponents-client please refer
to its security tracker page at:
https://security-tracker.debian.org/tracker/httpcomponents-client

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
