This update for virtualbox fixes the following issues :

  - Version bump to 6.1.20 (released April 20 2021 by     Oracle) Fixes boo#1183329 'virtualbox 6.1.18 crashes     when it runs nested VM' Fixes boo#1183125 'Leap 15.3     installation in Virtualbox without VBox integration'     Fixes CVE-2021-2264 and boo#1184542. The directory for     the <user>.start files for autostarting VMs is moved     from /etc/vbox to /etc/vbox/autostart.d. In addition,     the autostart service is hardened (by Oracle).

  - change the modalias for guest-tools and guest-x11 to get     them to autoinstall.

  - Own %(_sysconfdir)/X11/xinit/xinitrc.d as default     packages (eg systemd) no longer do so, breaking package     build.

  - Update fixes_for_leap15.3 for kernel API changes between     5.3.18-45 and 5.3.18-47.

  - update-extpack.sh: explicitly use https:// protocol for     authenticity. The http:// URL is currently redirected to     https:// but don't rely on this.

  - Add code to generate guest modules for Leap 15.2 and     Leap 15.3. The kernel versions do not allow window     resizing. Files 'virtualbox-kmp-files-leap' and     'vboxguestconfig.sh' are added

  - Fixes CVE-2021-2074, boo#1181197 and CVE-2021-2129,     boo#1181198.

  - Under some circumstances, shared folders are mounted as     root.

This update for virtualbox fixes the following issues :
