Description

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)

 - salt before 2015.5.5 leaks git usernames and passwords to the log. (CVE-2015-6918)

 - 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)
