Summary

Details

USN-6656-1 fixed several vulnerabilities in PostgreSQL. This update provides the corresponding updates for Ubuntu 16.04 LTS

It was discovered that PostgreSQL incorrectly handled dropping privileges when handling REFRESH MATERIALIZED VIEW CONCURRENTLY commands. If a user or automatic system were tricked into running a specially crafted command, a remote attacker could possibly use this issue to execute arbitrary SQL functions.
