Description

This module exploits a vulnerability in the Novell GroupWise Client gwcls1.dll
ActiveX. Several methods in the GWCalServer control use user provided data as
a pointer, which allows to read arbitrary memory and execute arbitrary code. This
module has been tested successfully with GroupWise Client 2012 on IE6 - IE9. The
JRE6 needs to be installed to achieve ASLR bypass.
