**According to the CVSS metric, user interaction is required (UI:R) and privileges required  is low (PR:L). What does that mean for this vulnerability?** An authorized attacker must send the user a malicious file and convince the user to open it.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** This vulnerability could lead to a contained execution environment escape. Please refer to AppContainer Isolation for more information.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** This vulnerability could be triggered when a user connects a Windows client to a malicious server.

**How could an attacker exploit the vulnerability?** To exploit this vulnerability, an attacker would need to send a specially crafted malicious MSMQ packet to a MSMQ server. This could result in remote code execution on the server side.

**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.

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

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

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

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

**Is the Preview Pane an attack vector for this vulnerability?** Yes, the Preview Pane is an attack vector.
