This proof of concept exploit triggers a null pointer vulnerability in OffsetChildren on Windows 7 32-bit. By mapping the null page an attacker can leverage this vulnerability to write to an arbitrary address.
930c6248c06d0f17df00bdda4843801b8c2604cfcf1b9138399dbc83fe37120bThis proof of concept exploit triggers a null pointer condition on Windows 7 32-bit, which can potentially be exploited on versions of Windows that allow mapping the null page (e.g. Windows 7 32-bit).
3bf1446b83cdd6c26177a31ebc1b3ce3549d04092ed485e00be882f09bb5eee1This proof of concept exploit 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.
01bafe1c271dd2a2ea9fadc32ab4da411c8c4eb30209e6634fd69a20fc0c4443The attached testcase crashes Windows 7 32-bit due to a pool buffer overflow in an ioctl handler. Enabling special on ndis.sys netio.sys and ntoskrnl helps to track down the issue, however it will crash due to a bad pool header without special pool as well.
3403491c7fbf36174b15a563987a49c4a34c9dfe661dfceec3ca982b901368adThe attached poc crashes 32-bit Windows 7 with a screen resolution of 1024x768 and 32bit color depth. The crash occurs during a memmove operation while copying the cursor content from unmapped memory. This could potentially be used by an attacker to leak kernel memory. When reproducing this issue in VMWare, it is necessary to remove VMWare tools. In QEMU the issue reproduces reliably.
4a4737c7da3e9d60d2829fc4216a2923ae3dd4946af77f8b03906129aa0fc6baThe attached testcase crashes Window 7 32-bit with Special Pool enabled on win32k.sys due to a use-after-free condition. The bug appears to be a race condition between two threads and multiple runs on the PoC might be required to trigger the bug. This is more reliable on systems with multiple cores.
