EulerOS 2.0 SP2 : postgresql (EulerOS-SA-2017-1232)

critical Nessus Plugin ID 103734

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the postgresql packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- It was found that authenticating to a PostgreSQL database account with an empty password was possible despite libpq's refusal to send an empty password. A remote attacker could potentially use this flaw to gain access to database accounts with empty passwords.
(CVE-2017-7546)

- An authorization flaw was found in the way PostgreSQL handled access to the pg_user_mappings view on foreign servers. A remote, authenticated attacker could potentially use this flaw to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so.
(CVE-2017-7547)

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

Solution

Update the affected postgresql packages.
