win32k Clipboard Bitmap – Use-After-Free
Source: https://code.google.com/p/google-security-research/issues/detail?id=533 This PoC triggers a crash on Windows 7 32-bit with Special Pool enabled on win32k.sys. The kernel crashes due to a use-after-free condition with bitmaps in the clipboard. --- Note that multiple PoC executions and simulated system activity may be required to trigger this issue.
