Vulnerability Information

Microsoft Office Component Use After Free Vulnerability - CVE-2014-6364

A remote code execution vulnerability exists in the context of the current 
user that is caused when Microsoft Word does not properly handle objects in 
memory while parsing specially crafted Office files. An attacker who 
successfully exploited this 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 complete control of the 
affected system. An attacker could then install programs; view, change, or 
delete data; or create new accounts with full user rights. Users whose 
accounts are configured to have fewer user rights on the system could be less
impacted than users who operate with administrative user rights.
