Microsoft Security Response Center

**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 take additional actions prior to exploitation to prepare the target environment.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of this vulnerability requires that a user trigger the payload in the application.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability would allow an attacker to disclose information stored on the system running the Azure RTOS GUIX Studio.

**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.

**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.

**How could an attacker exploit this vulnerability?** This vulnerability could be exploited if an authenticated user opens a specially crafted file locally or browses to that file on a network share when running an unpatched version of Windows. When the user browses or lists the maliciously crafted file that action could cause a crash of the operating system.

**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.

**Are there any special conditions necessary for this vulnerability to be exploitable?** Yes. This vulnerability is only exploitable if the MaxReceiveBuffer LDAP policy is set to a value higher than the default value. Systems with the default value of this policy would not be vulnerable. For more information, please see LDAP policies.

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by convincing a user to connect a Lightweight Directory Access Protocol (LDAP) client to a malicious LDAP server. When the vulnerability is successfully exploited this could allow the malicious server to gain remote code execution within the LDAP client.

**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 prepare the target environment to improve exploit reliability.
