Impact Level: Application.";

tag_insight = "The flaw exists due to the application loading libraries in an
insecure manner. This can be exploited to load arbitrary libraries by tricking
a user into opening a UENC file located on a remote WebDAV or SMB share.";

tag_solution = "No solution or patch was made available for at least one year
since disclosure of this vulnerability. Likely none will be provided anymore.
General solution options are to upgrade to a newer release, disable respective
features, remove the product or replace the product by another one.

A workaround is to disable loading of libraries from WebDAV and remote network
shares and to disable the WebClient service ";
