CVE-2016-3359

Name of the Vulnerable Software and Affected Versions Microsoft Excel versions 2007 SP3 through 2010 SP2 Office Compatibility Pack version SP3 Excel Viewer version (affected versions not specified)

Description The issue is caused by a memory corruption vulnerability that allows remote attackers to execute arbitrary code via a crafted document. This is due to the Office software failing to properly handle objects in memory. An attacker who successfully exploits the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with 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 of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software.

Recommendations For Microsoft Excel versions 2007 SP3 through 2010 SP2, update to a newer version to mitigate the risk. For Office Compatibility Pack version SP3, update to a newer version to mitigate the risk. For Excel Viewer, at the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider avoiding the use of specially crafted files until a patch is available.
