#Security Vulnerability

Heap-based buffer overflow in Windows Kernel-Mode Drivers allows an authorized attacker to elevate privileges locally.

**How could an attacker exploit this vulnerability?** To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then trigger an event that could exploit the vulnerability and save an invalid state to a database or trigger other unintended actions.

**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 type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**Why is this Synaptics CVE included in the Security Update Guide?** The vulnerability assigned to this CVE is Synaptics' Audio Effects component, which is consumed by Microsoft Windows. It is being documented in the Security Update Guide to announce that the latest builds of Windows are no longer vulnerable. Please see Security Update Guide Supports CVEs Assigned by Industry Partners for more information.

**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.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to some loss of confidentiality (C:L) but have no effect on integrity (I:N) or on availability (A:N). What does that mean for this vulnerability?** An attacker who successfully exploited the vulnerability could view some sensitive information (Confidentiality) but not all resources within the impacted component may be divulged to the attacker. The attacker cannot make changes to disclosed information (Integrity) or limit access to the resource (Availability).

Improper Link Resolution Before File Access ('Link Following') in Microsoft Exchange Server allows an authorized attacker to elevate privileges locally.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** The attacker would gain the rights of the user that is running the affected application.
