Synopsis
========

Multiple vulnerabilities in VirtualBox were found, the worst of which
allowing for privilege escalation.

Background
==========

The VirtualBox family provides powerful x86 virtualization products.

Affected packages
=================

    -------------------------------------------------------------------
     Package                     /  Vulnerable  /           Unaffected
    -------------------------------------------------------------------
  1  virtualbox-bin                  < 3.0.12                >= 3.0.12
  2  virtualbox-ose                  < 3.0.12                >= 3.0.12
  3  virtualbox-guest-additions      < 3.0.12                >= 3.0.12
  4  virtualbox-ose-additions        < 3.0.12                >= 3.0.12
    -------------------------------------------------------------------
     4 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
===========

Thomas Biege of SUSE discovered multiple vulnerabilities:

* A shell metacharacter injection in popen() (CVE-2009-3692) and a
  possible buffer overflow in strncpy() in the VBoxNetAdpCtl
  configuration tool.

* An unspecified vulnerability in VirtualBox Guest Additions
  (CVE-2009-3940).

Impact
======

A local, unprivileged attacker with the permission to run VirtualBox
could gain root privileges. A guest OS local user could cause a Denial
of Service (memory consumption) on the guest OS via unknown vectors.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All users of the binary version of VirtualBox should upgrade to the
latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=app-emulation/virtualbox-bin-3.0.12"

All users of the Open Source version of VirtualBox should upgrade to
the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=app-emulation/virtualbox-ose-3.0.12"

All users of the binary VirtualBox Guest Additions should upgrade to
the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=app-emulation/virtualbox-guest-additions-3.0.12"

All users of the Open Source VirtualBox Guest Additions should upgrade
to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose
">=app-emulation/virtualbox-ose-additions-3.0.12"
