How to fix?

Upgrade Debian:8 postgresql-9.4 to version 9.4.12-0+deb8u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql-9.4 package and not the postgresql-9.4 package as distributed by Debian. See How to fix? for Debian:8 relevant fixed versions and status.

It was found that some selectivity estimation functions in PostgreSQL before 9.2.21, 9.3.x before 9.3.17, 9.4.x before 9.4.12, 9.5.x before 9.5.7, and 9.6.x before 9.6.3 did not check user privileges before providing information from pg_statistic, possibly leaking information. An unprivileged attacker could use this flaw to steal some information from tables they are otherwise not allowed to access.
