Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2815 advisory.

Multiple security vulnerabilities have been discovered in Salt, a powerful remote execution manager, that allow for local privilege escalation on a minion, server side template injection attacks, insufficient checks for eauth credentials, shell and command injections or incorrect validation of SSL certificates.
For Debian 9 stretch, these problems have been fixed in version 2016.11.2+ds-1+deb9u7. We recommend that you upgrade your salt packages. For the detailed security status of salt please refer to its security tracker page at: https://security-tracker.debian.org/tracker/salt Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

For Debian 9 stretch, these problems have been fixed in version 2016.11.2+ds-1+deb9u7.
