This update provides virtualbox 5.2.20 and fixes the following security
vulnerabilities:

During key agreement in a TLS handshake using a DH(E) based ciphersuite
a malicious server can send a very large prime value to the client. This
will cause the client to spend an unreasonably long period of time
generating a key for this prime resulting in a hang until the client has
finished. This could be exploited in a Denial Of Service attack
(CVE-2018-0732).

Vulnerability in VirtualBox contains an easily exploitable vulnerability
that allows unauthenticated attacker with logon to the infrastructure
where VirtualBox executes to compromise VirtualBox. Successful attacks
require human interaction from a person other than the attacker and while
the vulnerability is in VirtualBox, attacks may significantly impact
additional products. Successful attacks of this vulnerability can result
in takeover of VirtualBox (CVE-2018-2909, CVE-2018-3287, (CVE-2018-3288,
CVE-2018-3289, CVE-2018-3290, CVE-2018-3291, CVE-2018-3292, CVE-2018-3293,
CVE-2018-3295, CVE-2018-3296, CVE-2018-3297, CVE-2018-3298).

Vulnerability in VirtualBox contains an easily exploitable vulnerability
that allows unauthenticated attacker with llow privileged attacker with
network access via VRDP to compromise VirtualBox. Successful attacks
require human interaction from a person other than the attacker and while
the vulnerability is in VirtualBox, attacks may significantly impact
additional products. Successful attacks of this vulnerability can result
in takeover of VirtualBox (CVE-2018-3294).
