CVE-2019-10209
Published: 8 August 2019
Postgresql, versions 11.x before 11.5, is vulnerable to a memory disclosure in cross-type comparison for hashed subplan.
From the Ubuntu Security Team
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).
