The debdiff attached brings in an upstream patch to fix
CVE-2019-1020014, hence closes #933801.
This is my first contribution to Debian Stable, please check for
beginners mistake ;)
Also, the devel-announce "Bits from the Stable Release Managers"
mentions:
* Fixes for security issues should be co-ordinated with the
Security Team, unless they have explicitly stated that they
will not issue an DSA for the bug (e.g. via a "no-dsa" marker
in the Security Tracker) [SECURITY-TRACKER]
So, is there anything else I should do here? Like, CC them or something?
Thanks!
Arnaud

+Subject: [PATCH] Fix a double free in the List functions
+
+The code was set up so that it would free the individual items and the data
+in `freeListData`, but there was already a Go `defer` to free the data item,
+resulting in a double free.
+
+Remove the `free` in `freeListData` and leave the original one.
+
+In addition, move the `defer` for freeing the list data before the error
+check, so that the data is also free in the error case. This just removes
+a minor leak.
+
+This vulnerability was discovered by:
+Jasiel Spelman of Trend Micro Zero Day Initiative and Trend Micro Team Nebula
