How to fix?

Upgrade Debian:10 libproxy to version 0.4.15-5+deb10u1 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 Debian. See How to fix? for Debian:10 relevant fixed versions and status.

url.cpp in libproxy through 0.4.15 is prone to a buffer overflow when PAC is enabled, as demonstrated by a large PAC file that is delivered without a Content-length header.
