CVE-2018-12557 Information

Description

An issue was discovered in Zuul 3.x before 3.1.0. If nodes become offline during the build the no_log attribute of a task is ignored. If the unreachable error occurred in a task used with a loop variable (e.g. with_items) the contents of the loop items would be printed in the console. This could lead to accidentally leaking credentials or secrets.
