Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is Prior to 6.1.18. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle VM VirtualBox accessible data as well as unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data. CVSS 3.1 Base Score 7.9 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N).

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.
