Where	From remote "From remote" describes other vulnerabilities where the attack vector doesn't require access to the system or a local network. This category covers services that are acceptable to expose to the Internet (e.g. HTTP, HTTPS, SMTP). It also covers client applications used on the Internet and certain vulnerabilities where it is reasonable to assume that a security conscious user can be tricked into performing certain actions.
Impact	System access This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.
Description	Two vulnerabilities have been reported in Microsoft Office, which can be exploited by malicious people to compromise a user's system. 1) An error when parsing cells comments in Excel files can be exploited to corrupt memory via a specially crafted Excel file. 2) An unspecified error when parsing Office files can be exploited to corrupt memory. Successful exploitation of the vulnerabilities may allow execution of arbitrary code.
