RedHat: RHSA-2017-1381:01 Important: sudo security update
Summary
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.
Security Fix(es):
* 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)
Red Hat would like to thank Qualys Security for reporting this issue.
