Details

It was discovered that PostgreSQL incorrectly handled partition routing. A
remote user could possibly use this issue to read arbitrary bytes of server
memory. This issue only affected Ubuntu 19.04. (CVE-2019-10129)

Dean Rasheed discovered that PostgreSQL incorrectly handled selectivity
estimators. A remote attacker could possibly use this issue to bypass row
security policies. (CVE-2019-10130)
