A DLL hijacking vulnerability has been discovered in OutSystems Service 
Studio 11 11.53.30 build 61739.
When a user open a .oml file (OutSystems Modeling Language), the 
application will load the following DLLs from the same directory:

av_libGLESv2.dll
libcef.DLL
user32.dll
d3d10warp.dll

Using a crafted DLL, it is possible to execute arbitrary code in the 
context of the current logged in user.
