The following security vulnerabilities were fixed (boo#1101667):

• CVE-2018-3005: Fixed an easily exploitable vulnerability that allowed
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks of this vulnerability can result in unauthorized ability to
  cause a partial denial
  of service (partial DOS) of Oracle VM VirtualBox.

• CVE-2018-3055: Fixed an easily exploitable vulnerability that allowed
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks require human interaction from a person other than the attacker
  and while the vulnerability is in Oracle VM VirtualBox, attacks may
  significantly impact additional products. Successful attacks of this
  vulnerability can result in unauthorized ability to cause a hang or
  frequently repeatable crash (complete DOS) of Oracle VM VirtualBox and
  unauthorized read access to a subset of Oracle VM VirtualBox accessible
  data.

• CVE-2018-3085: Fixed an easily exploitable vulnerability that allowed
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks require human interaction from a person other than the attacker
  and 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 read access to a subset of
  Oracle VM VirtualBox accessible data and unauthorized ability to cause a
  hang or frequently repeatable crash (complete DOS) of Oracle VM
  VirtualBox.

• CVE-2018-3086: Fixed an easily exploitable vulnerability that allowed
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks require human interaction from a person other than the attacker
  and while the vulnerability is in Oracle VM VirtualBox, attacks may
  significantly impact additional products. Successful attacks of this
  vulnerability can result in takeover of Oracle VM VirtualBox.

• CVE-2018-3087: Fixed an easily exploitable vulnerability that allowed
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks require human interaction from a person other than the attacker
  and while the vulnerability is in Oracle VM VirtualBox, attacks may
  significantly impact additional products. Successful attacks of this
  vulnerability can result in takeover of Oracle VM VirtualBox.

• CVE-2018-3088: Fixed an easily exploitable vulnerability allows
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks require human interaction from a person other than the attacker
  and while the vulnerability is in Oracle VM VirtualBox, attacks may
  significantly impact additional products. Successful attacks of this
  vulnerability can result in takeover of Oracle VM VirtualBox.

• CVE-2018-3089: Fixed an easily exploitable vulnerability allows
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks require human interaction from a person other than the attacker
  and while the vulnerability is in Oracle VM VirtualBox, attacks may
  significantly impact additional products. Successful attacks of this
  vulnerability can result in takeover of Oracle VM VirtualBox.

• CVE-2018-3090: Fixed an easily exploitable vulnerability allows
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks require human interaction from a person other than the attacker
  and while the vulnerability is in Oracle VM VirtualBox, attacks may
  significantly impact additional products. Successful attacks of this
  vulnerability can result in takeover of Oracle VM VirtualBox.

• CVE-2018-3091: Fixed an easily exploitable vulnerability allows
  unauthenticated attacker with logon to the infrastructure where Oracle
  VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful
  attacks require human interaction from a person other than the attacker
  and while the vulnerability is in Oracle VM VirtualBox, attacks may
  significantly impact additional products. Successful attacks of this
  vulnerability can result in unauthorized access to critical data or
  complete access to all Oracle VM VirtualBox accessible data.

The following bugs were fixed:

• OVF: case insensitive comparison of manifest attribute values, to
