+  * Fix CVE-2019-12086:
+    A Polymorphic Typing issue was discovered in jackson-databind. When
+    Default Typing is enabled (either globally or for a specific property) for
+    an externally exposed JSON endpoint, the service has the
+    mysql-connector-java jar (8.0.14 or earlier) in the classpath, and an
+    attacker can host a crafted MySQL server reachable by the victim, an
+    attacker can send a crafted JSON message that allows them to read arbitrary
+    local files on the server. This occurs because of missing
+    com.mysql.cj.jdbc.admin.MiniAdmin validation. (Closes: #929177)
