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

Description:

   - 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]

     them [bsc#1180687]
