CVE-2011-1277

Name of the Vulnerable Software and Affected Versions Microsoft Excel versions prior to the fixed version Office 2008 for Mac Open XML File Format Converter for Mac

Description The issue is related to the improper validation of record information during the parsing of Excel spreadsheets, which can lead to memory corruption. This allows remote attackers to execute arbitrary code or cause a denial of service. A remote code execution issue exists in the way Microsoft Excel handles specially crafted Excel files, potentially allowing an attacker to take complete control of an affected system, install programs, view, change, or delete data, or create new accounts with full user rights.

Recommendations For Microsoft Excel, update to a version that includes the fix for this issue. For Office 2008 for Mac, consider applying any available patches or updates that address this issue. For Open XML File Format Converter for Mac, restrict the use of this converter until a patch is available. As a temporary workaround, consider avoiding the use of specially crafted Excel files until the issue is resolved.
