Synopsis :

An application installed on the remote host is affected by multiple
vulnerabilities.

Description :

The version of the Oracle VM VirtualBox application installed on the
remote host is 5.0.x prior to 5.0.28 or 5.1.x prior to 5.1.8. It is,
therefore, affected by multiple vulnerabilities :

- Multiple unspecified flaws exist in the Core
subcomponent that allow a local attacker to gain
elevated privileges. (CVE-2016-5501, CVE-2016-5538)

- An unspecified flaw exists in the VirtualBox Remote
Desktop Extension (VRDE) subcomponent that allows an
unauthenticated, remote attacker to impact
confidentiality and integrity. (CVE-2016-5605)

- Multiple unspecified flaws exist in the Core
subcomponent that allow a local attacker to cause a
denial of service condition. (CVE-2016-5608,
CVE-2016-5613)

- An unspecified flaw exists in the Core subcomponent that
allows a local attacker to impact on integrity and
availability. (CVE-2016-5610)

- An unspecified flaw exists in the Core subcomponent that
allows a local attacker to disclose sensitive
information. (CVE-2016-5611)

- A flaw exists in the OpenSSL subcomponent, specifically
within the ssl_parse_clienthello_tlsext() function in
t1_lib.c due, to improper handling of overly large OCSP
Status Request extensions from clients. An
unauthenticated, remote attacker can exploit this, via
large OCSP Status Request extensions, to exhaust memory
resources, resulting in a denial of service condition.
(CVE-2016-6304)
