#Security Vulnerability

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if a Hyper-V Guest attacker successfully exploited this vulnerability is data from the Hyper-V Host.

**How would an attacker exploit this vulnerability?** An unauthenticated attacker could interact with the login screen of a vulnerable system in a specific manner to execute code on that system.

**I am running Windows 7 Service Pack 1 or Windows Server 2008 R2 Service Pack 1. Is there more information of which I need to be aware?** These operating systems are only affected by this vulnerability if either RDP 8.0 or RDP 8.1 is installed. If you do not have either of these versions of RDP installed on Windows 7 SP1 or Window Server 2008 R2 SP1, then you are not affected by this vulnerability.

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

**How could an attacker exploit this vulnerability?** For successful exploitation, a malicious certificate needs to be imported on an affected system. An authenticated attacker could remotely upload a certificate to the Server service.

**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, 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 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 a pointer leak to the process user-mode address space in the internal memory of the application that is using GDI+.

**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 the contents of Kernel memory. An attacker could read the contents of Kernel memory from a user mode process.

**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 invest time in repeated exploitation attempts through sending constant or intermittent data.
