Microsoft Windows Cursor Object Potential Memory Leak
Posted by deepcore on November 25, 2015 – 5:49 pm
The attached poc crashes 32-bit Windows 7 with a screen resolution of 1024×768 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.
