Summary
postgresql-10, postgresql-11, postgresql-9.5 vulnerabilities
Details

Tom Lane discovered that PostgreSQL did not properly restrict functions declared as "SECURITY DEFINER". An attacker could use this to execute arbitrary SQL with the permissions of the function owner. (CVE-2019-10208)

Andreas Seltenreich discovered that PostgreSQL did not properly handle user-defined hash equality operators. An attacker could use this to expose sensitive information (arbitrary PostgreSQL server memory). This issue only affected Ubuntu 19.04. (CVE-2019-10209)
