"When sudo is configured to allow a user to run commands as an
arbitrary user via the ALL keyword in a Runas specification, it is
possible to run commands as root by specifying the user ID -1 or
4294967295.

This can be used by a user with sufficient sudo privileges to run
commands as root even if the Runas specification explicitly disallows
root access as long as the ALL keyword is listed first in the Runas
specification. (CVE-2019-14287)

Further details can be found here:
https://www.sudo.ws/alerts/minus_1_uid.html

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)

vulnerability from the CVE link(s) in the References section.

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) :

* sudo: Privilege escalation via 'Runas' specification with 'ALL'
keyword (CVE-2019-14287)

When sudo is configured to allow a user to run commands as an
arbitrary user via the ALL keyword in a Runas specification, it is
possible to run commands as root by specifying the user ID -1 or
4294967295.

This can be used by a user with sufficient sudo privileges to run
commands as root even if the Runas specification explicitly disallows
root access as long as the ALL keyword is listed first in the Runas
specification.

Log entries for commands run this way will list the target user as
4294967295 instead of root. In addition, PAM session modules will not
be run for the command."

"When sudo is configured to allow a user to run commands as an
arbitrary user via the ALL keyword in a Runas specification, it is
possible to run commands as root by specifying the user ID -1 or
4294967295.

This can be used by a user with sufficient sudo privileges to run
commands as root even if the Runas specification explicitly disallows
root access as long as the ALL keyword is listed first in the Runas
specification. (CVE-2019-14287)
