. CVE-2011-1276 ID CVE-2011-1276 Summary Buffer overflow in Microsoft Excel 2002 SP3, 2003 SP3, and 2007 SP2; Office 2004 and 2008 for Mac; Open XML File Format Converter for Mac; Excel Viewer SP2; and Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted Excel spreadsheet, related to improper validation of record information, aka 'Excel Buffer Overrun Vulnerability.' An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process.

This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow. Buffer Overflow via Symbolic Links. This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation.

All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process. Buffer Overflow in Local Command-Line Utilities. This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

DESCRIPTION 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 Excel file. Specific values within this file can trigger a memory corruption vulnerability and may allow arbitrary code execution. ANALYSIS 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. DETECTION The following Microsoft products are vulnerable: Excel 2002 SP3 Excel 2002 SP3 Excel 2003 SP3 Office 2004 for Mac Office 2008 for Mac Open XML File Format Converter for Mac V.
