high Nessus Plugin ID 139629

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Andres Freund found an issue in the PostgreSQL database system where an uncontrolled search path could allow users to run arbitrary SQL functions with elevated priviledges when a superuser runs certain `CREATE EXTENSION' statements.

For Debian 9 stretch, this problem has been fixed in version 9.6.19-0+deb9u1.

We recommend that you upgrade your posgresql-9.6 packages.

For the detailed security status of posgresql-9.6 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/posgresql-9.6

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 posgresql-9.6 package.
