Package : httpcomponents-client
Version : 4.5.2-2+deb9u1
CVE ID : CVE-2020-13956
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.
