Microsoft Security Response Center

**There are multiple update packages available for some of the affected software. Do I need to install all the updates listed in the Security Updates table for the software?** Yes. Customers should apply all updates offered for the software installed on their systems. If multiple updates apply, they can be installed in any order.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of certain memory address within kernel space. Knowing the exact location of kernel memory could be potentially leveraged by an attacker for other malicious activities.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker would have to send the victim a malicious file that the victim would have to execute.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could bypass Office macro policies used to block untrusted or malicious files.

**According to the CVSS metric, the Attack Vector is Physical (AV:P). What does that mean for this vulnerability?** An attacker needs physical access to the target computer to plug in a malicious USB drive.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of certain memory address within kernel space. Knowing the exact location of kernel memory could be potentially leveraged by an attacker for other malicious activities.
