This update for salt fixes one security issue and bugs. The following security issue has been fixed :

  - CVE-2017-12791: Directory traversal vulnerability in     minion id validation allowed remote minions with     incorrect credentials to authenticate to a master via a     crafted minion ID (bsc#1053955).

The update package also includes non-security fixes. See advisory for details.

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

SaltStack reports :

Correct a flaw in minion id validation which could allow certain minions to authenticate to a master despite not having the correct credentials. To exploit the vulnerability, an attacker must create a salt-minion with an ID containing characters that will cause a directory traversal. Credit for discovering the security flaw goes to:

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4769-1 advisory.

  - Multiple unspecified vulnerabilities in Salt (aka SaltStack) before 2014.1.10 allow local users to have an     unspecified impact via vectors related to temporary file creation in (1) seed.py, (2) salt-ssh, or (3)     salt-cloud. (CVE-2014-3563)

  - win_useradd, salt-cloud and the Linode driver in salt 2015.5.x before 2015.5.6, and 2015.8.x before     2015.8.1 leak password information in debug logs. (CVE-2015-6941)

  - Directory traversal vulnerability in minion id validation in SaltStack Salt before 2016.11.7 and 2017.7.x     before 2017.7.1 allows remote minions with incorrect credentials to authenticate to a master via a crafted     minion ID. (CVE-2017-12791)

  - Directory traversal vulnerability in minion id validation in SaltStack Salt before 2016.3.8, 2016.11.x     before 2016.11.8, and 2017.7.x before 2017.7.2 allows remote minions with incorrect credentials to     authenticate to a master via a crafted minion ID. NOTE: this vulnerability exists because of an incomplete     fix for CVE-2017-12791. (CVE-2017-14695)

  - SaltStack Salt before 2016.3.8, 2016.11.x before 2016.11.8, and 2017.7.x before 2017.7.2 allows remote     attackers to cause a denial of service via a crafted authentication request. (CVE-2017-14696)

  - Directory Traversal vulnerability in salt-api in SaltStack Salt before 2017.7.8 and 2018.3.x before     2018.3.3 allows remote attackers to determine which files exist on the server. (CVE-2018-15750)

  - SaltStack Salt before 2017.7.8 and 2018.3.x before 2018.3.3 allow remote attackers to bypass     authentication and execute arbitrary commands via salt-api(netapi). (CVE-2018-15751)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
