    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]
