[1] "CVE-2017-3167 7.4 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H The supported version that is affected is 5.3. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Secure Global Desktop (SGD). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Secure Global Desktop (SGD) accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Secure Global Desktop (SGD). CVE-2017-10392 7.3 AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:H The supported version that is affected is Prior to 5.1.30. 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 ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox as well as unauthorized update, insert or delete access to some of Oracle VM VirtualBox accessible data and unauthorized read access to a subset of Oracle VM VirtualBox accessible data. CVE-2017-10407 7.3 AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:H The supported version that is affected is Prior to 5.1.30. 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 ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox as well as unauthorized update, insert or delete access to some of Oracle VM VirtualBox accessible data and unauthorized read access to a subset of Oracle VM VirtualBox accessible data. CVE-2017-10408 7.3 AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:H The supported version that is affected is Prior to 5.1.30. 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 ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox as well as unauthorized update, insert or delete access to some of Oracle VM VirtualBox accessible data and unauthorized read access to a subset of Oracle VM VirtualBox accessible data. CVE-2017-3733 5.9 AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N The supported version that is affected is Prior to 5.1.30. Difficult to exploit vulnerability allows unauthenticated attacker with network access via TLS to compromise Oracle VM VirtualBox. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data. CVE-2017-10428 5.0 AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:L The supported version that is affected is Prior to 5.1.30. Difficult to exploit 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 update, insert or delete access to some of 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 partial denial of service (partial DOS) of Oracle VM VirtualBox." [2] MITIGATION Oracle states: "Due to the threat posed by a successful attack, Oracle strongly recommends that customers apply CPU fixes as soon as possible. Until you apply the CPU fixes, it may be possible to reduce the risk of successful attack by blocking network protocols required by an attack. For attacks that require certain privileges or access to certain packages, removing the privileges or the ability to access the packages from users that do not need the privileges may help reduce the risk of successful attack. Both approaches may break application functionality, so Oracle strongly recommends that customers test changes on non-production systems. Neither approach should be considered a long-term solution as neither corrects the underlying problem."
