CVE-2020-25219
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.
For Debian 9 Stretch, these problems have been fixed in version 0.4.14-2+deb9u1.
We recommend that you upgrade your libproxy packages.
