In postgresql 9.3.x before 9.3.21, 9.4.x before 9.4.16, 9.5.x before 9.5.11, 9.6.x before 9.6.7 and 10.x before 10.2, pg_upgrade creates file in current working directory containing the output of `pg_dumpall -g` under umask which was in effect when the user invoked pg_upgrade, and not under 0077 which is normally used for other temporary files. This can allow an authenticated attacker to read or modify the one file, which may contain encrypted or unencrypted database passwords. The attack is infeasible if a directory mode blocks the attacker searching the current working directory or if the prevailing umask blocks the attacker opening the file.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2566 advisory.

  - postgresql: Memory disclosure in JSON functions (CVE-2017-15098)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of PostgreSQL installed on the remote host is 9.3.x prior to 9.3.21, 9.4.x prior to 9.4.16, 9.5.x prior to 9.5.11, 9.6.x prior to 9.6.7, or 10.x prior to 10.2. It is, therefore, affected by multiple vulnerabilities.

It was discovered that PostgreSQL incorrectly handled certain temp files. An attacker could possibly use this to access sensitive information.

The PostgreSQL project reports :

- CVE-2018-1052: Fix the processing of partition keys containing multiple expressions (only for PostgreSQL-10.x)

- CVE-2018-1053: Ensure that all temporary files made with 'pg_upgrade' are non-world-readable

A vulnerabilities has been found in the PostgreSQL database system :

CVE-2018-1053

Tom Lane discovered that pg_upgrade, a tool used to upgrade PostgreSQL database clusters, creates temporary files containing password hashes that are world-readable.

For Debian 7 'Wheezy', this problem has been fixed in version 9.1.24lts2-0+deb7u2.

We recommend that you upgrade your postgresql-9.1 packages.
