The Trend Micro AntiVirus scan engine before 8.550-1001, as used in Trend Micro PC-Cillin Internet Security 2007, and Tmxpflt.sys 8.320.1004 and 8.500.0.1002, has weak permissions (Everyone:Write) for the \\.\Tmfilter device, which allows local users to send arbitrary content to the device via the IOCTL functionality. NOTE: this can be leveraged for privilege escalation by exploiting a buffer overflow in the handler for IOCTL 0xa0284403.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
