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	A vulnerability has been reported in Microsoft Office OneNote, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to missing input validation when processing a URI using the "onenote://" protocol handler. This can be exploited to e.g. place files on a user's system in semi-arbitrary locations or obtain all OneNote Notebooks from the user's system via a specially crafted OneNote URI. NOTE: According to the vendor, the vulnerability exists in a shared Office component, but can only be exploited on systems with OneNote 2007 installed.
Solution	Apply patches.
