1.Description:
The tmtdi.sys kernel driver distributed with Trend Micro Titanium Maximum Security 2011 contains a pointer overwrite vulnerability in the handling of IOCTL 0x220404.
Exploitation of this issue allows an attacker to execute arbitrary code within the kernel.
An attacker would need local access to a vulnerable computer to exploit this vulnerability.
Affected application: Trend Micro Titanium Maximum Security 2011, up to date version 3.0.1303.
Affected file: tmtdi.sys version 6.5.0.1234.
2.Vulnerability details:
IoCtl handler of \\.\tmtdi device drivesr:
