漏洞信息
The sudo packages contain the sudo utility which allows system administrators to provide certain users with the permission to execute privileged commands, which are used for system management purposes, without having to log in as root.
A flaw was found in the way sudo parsed tty information from the process status file in the proc filesystem. A local user with privileges to execute commands via sudo could use this flaw to escalate their privileges to root. (CVE-2017-1000367)
