低危 pg_upgrade在普遍的umask下创建敏感元数据文件
CVE编号
CVE-2018-1053利用情况
暂无补丁情况
官方补丁披露时间
2018-02-10漏洞描述
在9.3.21之前的postgresql 9.3.x，9.4.16之前的9.4.x，9.5.11之前的9.5.x，9.6.7之前的9.6.x和10.2之前的10.x，pg_upgrade在包含输出的当前工作目录中创建文件在umask下的`pg_dumpall -g`，当用户调用pg_upgrade时生效，而不是在0077下，它通常用于其他临时文件。这可以允许经过身份验证的攻击者读取或修改一个文件，该文件可能包含加密或未加密的数据库密码。如果目录模式阻止攻击者搜索当前工作目录，或者流行的umask阻止攻击者打开文件，则攻击是不可行的。解决建议
目前厂商已发布升级补丁以修复漏洞，补丁获取链接：https://www.postgresql.org/about/news/1829/受影响软件情况
