Microsoft Windows Kernel ATMFD.DLL NamedEscape 0x250D Pool Corruption
Posted Jan 10, 2018
Authored by Google Security Research, mjurczyk

The Microsoft Windows OpenType ATMFD.DLL kernel-mode font driver has an undocumented "escape" interface, handled by the standard DrvEscape and DrvFontManagement functions implemented by the module. The interface is very similar to Buffered IOCTL in nature, and handles 13 different operation codes in the numerical range of 0x2502 to 0x2514. It is accessible to user-mode applications through an exported (but not documented) gdi32!NamedEscape function, which internally invokes the NtGdiExtEscape syscall.

Microsoft Windows Kernel ATMFD.DLL Out-Of-Bounds Read
Posted Jan 10, 2018
Authored by Google Security Research, mjurczyk

The Microsoft Windows OpenType ATMFD.DLL kernel-mode driver lacks any sort of sanitization of various 32-bit offsets found in .MMM files (Multiple Master Metrics), and instead uses them blindly while loading Type 1 Multiple-Master fonts in the system.
