Hi there,

This is a buster proposed update to fix CVE-2019-13952 aka #932407. This
is an old and really minor vulnerability, which I honestly had forgotten
about. It's easy and thus still good to fix.

I've packaged this as 2.4.3-1 (from 2.4.2-1). While technically a new
upstream release, it was released solely to contain this (two-line) fix,
with no other changes, as you can also see below. 2.4.3-1 never existed
in unstable either (it went to 3.5.0-1 directly), so it should be safe
for upgrades as well. Hope that's OK!

Diff below. Thank you for your consideration!

Regards,
Faidon
