What is CVE-2018-1053?

In PostgreSQL versions prior to 9.3.21, 9.4.16, 9.5.11, 9.6.7, and 10.2, a flaw exists in the pg_upgrade utility where it writes output files in the current working directory without ensuring secure file permissions. As a result, authenticated users may gain access to sensitive data, including database passwords, if file permissions are improperly set.
