An update that solves three vulnerabilities and has one
errata is now available.

Description:

This update for sudo fixes the following issues:

- A Heap-based buffer overflow in sudo could be exploited to allow a user
to gain root privileges [bsc#1181090,CVE-2021-3156]
- It was possible for a user to test for the existence of a directory due
to a Race Condition in `sudoedit` [bsc#1180684,CVE-2021-23239]
- A Possible Symlink Attack vector existed in `sudoedit` if SELinux was
running in permissive mode [bsc#1180685, CVE-2021-23240]
- It was possible for a User to enable Debug Settings not Intended for
them [bsc#1180687]
