The vulnerability could allow elevation of privilege if a malicious executable is placed on an affected system by an attacker, and then another user logs on later and runs the malicious executable. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. This security update is rated Important for Microsoft Office for Mac 2011. For more information, see the subsection, Affected and Non-Affected Software, in this section. Affected Software Microsoft Office for Mac 2011 Vulnerability Information Office for Mac Improper Folder Permissions Vulnerability - CVE-2012-1894 An elevation of privilege vulnerability exists in the way that folder permissions are set in certain Microsoft Office for Mac installations. An attacker could place a malicious executable in the Microsoft Office 2011 folder. If a user later logs on and runs the malicious executable, attacker- provided code can be made to execute in the security context of the current user. If the user runs the malicious executable as an administrator, the attacker could take complete control over an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The attacker would only be able to gain elevated privileges on the affected Mac computer if a user executed the malicious executable. This is not a direct elevation of privilege, but rather it is a luring attack. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
