Description:   Two vulnerabilities were reported in Microsoft Jet. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create a specially crafted Excel file that, when loaded by the target user on an affected version of Microsoft Windows, will trigger a buffer overflow in the Microsoft JET Database Engine and execute arbitrary code on the target system. The code will run with the privileges of the target user.

Honggang Ren of Fortinet's FortiGuard Labs, Pengsu Cheng of Trend Micro Security Research (via Trend Micro's Zero Day Initiative), and Lucas Leong (@wmliang) of Trend Micro Security Research (via Trend Micro's Zero Day Initiative) reported these vulnerabilities.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.
Solution:   The vendor has issued a fix.
