Ubuntu 14.04 LTS / 16.04 LTS : PostgreSQL vulnerabilities (USN-3066-1)

high Nessus Plugin ID 93047

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3066-1 advisory.

Heikki Linnakangas discovered that PostgreSQL incorrectly handled certain nested CASE/WHEN expressions. A remote attacker could possibly use this issue to cause PostgreSQL to crash, resulting in a denial of service. (CVE-2016-5423)

Nathan Bossart discovered that PostgreSQL incorrectly handled special characters in database and role names. A remote attacker could possibly use this issue to escalate privileges. (CVE-2016-5424)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
