Heap-based buffer overflow in Microsoft Office allows an authorized attacker to execute code locally.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** A race condition is triggered when the admin begins administering from the host system and not a guest or nested guest.

**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.

Deserialization of untrusted data in Microsoft Office SharePoint allows an authorized attacker to execute code over a network.

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

Use after free in Desktop Windows Manager allows an authorized attacker to execute code locally.

**Is the Preview Pane an attack vector for this vulnerability?** Yes, the Preview Pane is an attack vector.

**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.

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