Debian DLA-1051-1 : postgresql-9.1 security update

critical Nessus Plugin ID 102368

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been found in the PostgreSQL database system :

CVE-2017-7486

Andrew Wheelwright discovered that user mappings were insufficiently restricted.

CVE-2017-7546

In some authentication methods empty passwords were accepted.

CVE-2017-7547

User mappings could leak data to unprivileged users.

We recommend that you upgrade your postgresql-9.1 packages.

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

Solution

Upgrade the affected packages.
