Debian DLA-2294-1 : salt security update

critical Nessus Plugin ID 139094
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security update.

Description

Two issues have been found in salt, a remote manager to administer servers.

These issues are related to remote hackers bypassing authentication to execute arbitrary commands and getting informations about files on the server

For Debian 9 stretch, these problems have been fixed in version 2016.11.2+ds-1+deb9u5.

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

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.
