Name of the Vulnerable Software and Affected Versions Microsoft Excel versions 2007 SP3 through 2016 Office Compatibility Pack version SP3 Excel Viewer version (affected versions not specified)

Description The issue is caused by a memory corruption vulnerability in Microsoft Excel, allowing remote attackers to execute arbitrary code via a crafted document. This is due to the software's failure to properly handle objects in memory, which can be exploited by an attacker to run arbitrary code in the context of the current user. If the current user has administrative user rights, an attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights. Exploitation requires a user to open a specially crafted file with an affected version of Microsoft Office software.

Recommendations For Microsoft Excel versions 2007 SP3 through 2016, update to a version that includes the fix for this issue. For Office Compatibility Pack version SP3, update to a version that includes the fix for this issue. For Excel Viewer, at the moment, there is no information about a newer version that contains a fix for this vulnerability.
