**According to the CVSS metric, attack vector is (AV:N) and user interaction is none (UI:N). What does that mean for this vulnerability?** This can happen without user intervention. An attacker can use an uninitialized function pointer being called when decoding a JPEG image. This can be embedded in Office and 3rd party documents/files

**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.

Time-of-check time-of-use (toctou) race condition in Windows NTFS allows an unauthorized attacker to disclose information locally.

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

Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an unauthorized attacker to perform spoofing over a network.

Allocation of resources without limits or throttling in Windows DirectX allows an authorized attacker to deny service over a network.

Weak authentication in Remote Desktop Client allows an unauthorized attacker to perform spoofing over a network.

Heap-based buffer overflow in Windows Cloud Files Mini Filter Driver allows an authorized attacker to elevate privileges locally.

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).
