Synopsis

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-3476-1 advisory.

 Dawid Golunski discovered that the postgresql-common pg_ctlcluster script incorrectly handled symlinks. A local attacker could possibly use this issue to escalate privileges. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-1255)

 It was discovered that the postgresql-common helper scripts incorrectly handled symlinks. A local attacker could possibly use this issue to escalate privileges. (CVE-2017-8806)
