Microsoft Security Response Center

Integer overflow or wraparound in Microsoft Graphics Component allows an authorized attacker to execute code locally.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited the vulnerability could evade Mark of the Web (MOTW) defenses.

**What actions do customers need to take to protect themselves from this vulnerability?** Customers who have disabled Automatic Extension Upgrades or would like to upgrade an extension immediately must manually update their Azure Monitor Agent to the latest version. For more information on how to perform a manual update, see Manage Azure Monitor Agent.

Heap-based buffer overflow in Microsoft Graphics Component allows an authorized attacker to elevate privileges locally.

Improper link resolution before file access ('link following') in Visual Studio allows an unauthorized attacker to elevate privileges over a network.

Missing synchronization in Windows Hyper-V allows an authorized attacker to deny service over an adjacent network.

Time-of-check time-of-use (toctou) race condition in Microsoft Windows QoS scheduler allows an authorized attacker to elevate privileges locally.

**How could an attacker exploit this vulnerability?** An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server via the Routing and Remote Access Service (RRAS) Snap-in. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.

Use after free in Windows Connected Devices Platform Service allows an unauthorized attacker to execute code over a network.

**According to the CVSS score, the attack vector is adjacent (AV:A). What does this mean for this vulnerability?** This attack is limited to systems connected to the same network segment as the attacker. The attack cannot be performed across multiple networks (for example, a WAN) and would be limited to systems on the same network switch or virtual network.
