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

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"
