This vulnerability allows remote attackers to corrupt heap memory on vulnerable installations of Microsoft Office Excel. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within processing of pivotField objects. A specially crafted spreadsheet can cause Excel to write information past the end of a heap-allocated buffer. An attacker may be able to leverage this vulnerability to execute arbitrary code under the context of the current process.
