官方补丁披露时间
2021-06-15漏洞描述
A flaw was found in the use of insufficiently random values in Ansible. Two random password lookups of the same length generate the equal value as the template caching action for the same file since no re-evaluation happens. The highest threat from this vulnerability would be that all passwords are exposed at once for the file. This flaw affects Ansible Engine versions before 2.9.6.解决建议
建议您更新当前系统或软件至最新版，完成漏洞的修复。
