DESCRIPTION:
A vulnerability has been discovered in YLoader, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the application bundling a
vulnerable version of the Prof-UIS library, which loads libraries
(e.g. dwmapi.dll) in an insecure manner. This can be exploited to
load arbitrary libraries by tricking a user into e.g. opening a TXT
file located on a remote WebDAV or SMB share

Successful exploitation allows execution of arbitrary code, but
requires that files are opened via the Windows Explorer "Open With"
menu.

For more information:
SA41578

The vulnerability is confirmed in version 3.0.0.0. Other versions may
also be affected.

SOLUTION:
Do not open untrusted files.
