Upgrade Ubuntu:20.04 libproxy to version 0.4.15-10ubuntu1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libproxy package and not the libproxy package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion.
