Buffer over-read in Microsoft Office Excel allows an unauthorized attacker to execute code locally.

Improper neutralization of special elements used in a command ('command injection') in Visual Studio allows an unauthorized attacker to execute code locally.

**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 first prepare the target so that it uses Edge in Internet Explorer Mode.

**According to the CVSS metric, the attack vector is network (AV:N) and user interaction is required (UI:R). What is the target context of the remote code execution?** This attack requires a user to open a specially crafted file from the attacker to initiate remote code execution.

Heap-based buffer overflow in Windows Media allows an unauthorized attacker to execute code over a network.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** In a web-based attack scenario, an attacker could host a website or server that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file.

Use after free in Windows Common Log File System Driver allows an authorized attacker to elevate privileges locally.

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

Heap-based buffer overflow in Windows Win32K - GRFX allows an unauthorized attacker to execute code locally.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of certain kernel memory content.
