  - A Incorrect Authorization vulnerability in chkstat of SUSE Linux Enterprise Server 12-SP5; openSUSE Leap
    15.3, openSUSE Leap 15.4, openSUSE Leap Micro 5.2 did not consider group writable path components,
    allowing local attackers with access to a group what can write to a location included in the path to a
