**According to the CVSS metric, the attack vector is local (AV:L) while user interaction is required (UI:R). What does that mean for this vulnerability?** An attacker can trick a local user on a vulnerable system into mounting a specially crafted VHD that would then trigger the vulnerability.

**According to the CVSS metric, user interaction is required (UI:R) and privileges required is Low (PR:L). What does that mean for this vulnerability?** An authorized attacker with low privileges creates a scheduled task that is set to run when a user logs on and spoofs interfaces that belong to many services so the victim can connect to the attacker's server instead of the original.

Use of a broken or risky cryptographic algorithm in Office Developer Platform allows an authorized attacker to bypass a security feature locally.

Heap-based buffer overflow in SQL Server allows an authorized attacker to execute code over a network.

**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.

**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 prepare the target environment to improve exploit reliability.

Use after free in Windows Notification allows an authorized attacker to elevate privileges locally.

Improper access control in Microsoft PC Manager allows an authorized attacker to elevate privileges locally.

Use after free in Microsoft Input Method Editor (IME) allows an unauthorized attacker to elevate privileges over a network.

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