Debian DLA-2223-1 : salt security update

critical Nessus Plugin ID 136979

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were discovered in package salt, a configuration management and infrastructure automation software.

CVE-2020-11651

The salt-master process ClearFuncs class does not properly validate method calls. This allows a remote user to access some methods without authentication. These methods can be used to retrieve user tokens from the salt master and/or run arbitrary commands on salt minions.

CVE-2020-11652

The salt-master process ClearFuncs class allows access to some methods that improperly sanitize paths. These methods allow arbitrary directory access to authenticated users.

For Debian 8 'Jessie', these problems have been fixed in version 2014.1.13+ds-3+deb8u1.

We recommend that you upgrade your salt 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.
