Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Andrew Krasichkov discovered that the PostgreSQL client library incorrectly reset its internal state between connections. A remote attacker could possibly use this issue to bypass certain client-side connection security features. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2018-10915)

It was discovered that PostgreSQL incorrectly checked authorization on certain statements. A remote attacker could possibly use this issue to read arbitrary server memory or alter certain data. (CVE-2018-10925).

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

Solution

Update the affected postgresql-10, postgresql-9.3 and / or postgresql-9.5 packages.
