It was found that Internet Explorer allows the disclosure of local file
names. This issue exists due to the fact that Internet Explorer behaves
different for file:// URLs pointing to existing and non-existent files.
When used in combination with HTML5 sandbox iframes it is possible to
use this behavior to find out if a local file exists. This technique
only works on Internet Explorer 10 & 11 since these support the HTML5
sandbox. Also it is not possible to do this from a regular website as
file:// URLs are blocked all together. The attack must be performed
locally (works with Internet zone Mark of the Web) or from a share.

Multiple DLL side loading vulnerabilities were found in various COM
components.
These issues can be exploited by loading various these components as an
embedded
OLE object. When instantiating a vulnerable object Windows will try to
load one
or more DLLs from the current working directory. If an attacker
convinces the
victim to open a specially crafted (Office) document from a directory
also
containing the attacker's DLL file, it is possible to execute arbitrary
code with
the privileges of the target user. This can potentially result in the
attacker
taking complete control of the affected system.
