Microsoft Excel SCENARIO Record Memory Corruption Vulnerability
Excel is the spreadsheet application included with Microsoft Corp.'s Office productivity software suite. More information is available at the following website:
Remote exploitation of a memory corruption vulnerability in Microsoft Corp.'s Excel could allow an attacker to execute arbitrary code with the privileges of the current user.
The vulnerability occurs when Excel parses a specially crafted SCENARIO record in an Excel file. Specific values of length filed within that record can trigger a memory corruption vulnerability and may allow arbitrary code execution.
Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the user opening the file. To exploit this vulnerability, an attacker needs to convince a user to open a malicious file. Attackers typically accomplish this by e-mailing a targeted user the file or hosting the file on a Web page.
The following Microsoft products are vulnerable:
