#Security Vulnerability

**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 gather information specific to the environment of the targeted component.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Successful exploitation of this vulnerability by an attacker requires a user to first reboot their machine.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of initialized or uninitialized memory in the process heap.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted file to be compromised by the attacker.

**The Security Updates table indicates that this vulnerability affects all supported versions of Microsoft Windows except Windows Server 2008, Windows Server 2008 R2, and Windows Server 2012. Why are IE Cumulative updates listed for Windows Server 2012 R2?** While Microsoft has announced retirement of the Internet Explorer 11 application on certain platforms and the Microsoft Edge Legacy application is deprecated, the underlying MSHTML, EdgeHTML, and scripting platforms are still supported. The MSHTML platform is used by Internet Explorer mode in Microsoft Edge as well as other applications through WebBrowser control. The EdgeHTML platform is used by WebView and some UWP applications. The scripting platforms are used by MSHTML and EdgeHTML but can also be used by other legacy applications. Updates to address vulnerabilities in the MSHTML platform and scripting engine are included in the IE Cumulative Updates; EdgeHTML and Chakra changes are not applicable to those platforms. To stay ...

**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** Exploiting this vulnerability requires an attacker to be within proximity of the target system to send and receive radio transmissions.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**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. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is memory layout - the vulnerability allows an attacker to collect information that facilitates predicting addressing of the memory.

**According to the CVSS metric, the attack vector is adjacent (AV:A). What does that mean for this vulnerability?** Exploiting this vulnerability requires an attacker to be within proximity of the target system to send and receive radio transmissions.
