Description:   Several vulnerabilities were reported in Microsoft Excel. 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, will trigger a buffer overflow and execute arbitrary code on the target system. The code will run with the privileges of the target user.

Specially crafted DATETIME or COLINFO records can trigger these flaws, as can specially crafted Lotus 1-2-3 files.

Microsoft credits Manuel Santamarina Suarez and TippingPoint and the NSFocus Security Team with reporting two of these vulnerabilities.
