What remains unknown

Whether your environment runs an affected product and version is not established by this public lookup.
Reachability, compensating controls, and successful exploitation in a specific environment are not checked.

What this is

In Sudo through 1.9.17p2 before 3e474c2, a failure of a setuid, setgid, or setgroups call, during a privilege drop before running the mailer, is not a fatal error and can lead to privilege escalation.
