On tuesday a notice for CVE-2019-14287 affecting Sudo versions prior to 1.8.28.

CVE-2019-11253 is a vulnerability that 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.

This vulnerability has been given an initial severity of High, with a score of 7 (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H).

We have patched all our systems to make use of the patched sudo version.
