Apache YuniKorn 1.8.0 and later, if configured with the LDAP group resolver, crashes due to an out of bounds read processing group membership entries.If the LDAP server returns a group membership entry, memberOf attribute, for a user specified in the pod the server crashes if a membership record does not start with "CN=". This only affects install that have the non default LDAP group provider configured. Users are recommended to upgrade to version 1.10.0, which fixes this issue.
