Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network.

**According to the CVSS metric, the attack vector is network (AV:N), user interaction is required (UI:R), and privileges required are none (PR:N). What does that mean for this vulnerability?** Exploitation of this vulnerability requires an unauthorized attacker to wait for a user to initiate a connection to a malicious server that the attacker has set up prior to the user connecting.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

Use after free in Microsoft Office allows an unauthorized attacker to execute code 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.

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

Use after free in Microsoft Windows Search Component allows an authorized attacker to elevate privileges locally.

Buffer over-read in Storage Port Driver allows an authorized attacker to disclose information locally.

Integer overflow or wraparound in Virtual Hard Disk (VHDX) allows an unauthorized attacker to execute code locally.
