From c3faeb852866a2fc8ae9cd6f8cf91947bd42b538 Mon Sep 17 00:00:00 2001 From: Andy Shaw Date: Wed, 25 Sep 2019 09:17:01 +0200 Subject: Fix CVE-2019-16168 in SQLite v3.29.0 is the latest and there is no indication as to when the next release is so we will apply this separately for now and it can be reverted once it is in a release that we ship with.
