**Is the Preview Pane an attack vector for this vulnerability?** No, the Preview Pane is not an attack vector.

Heap-based buffer overflow in Windows Telephony Service allows an unauthorized attacker to execute code over a network.

Heap-based buffer overflow in Windows Telephony Service allows an unauthorized attacker to execute code over a network.

**According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** This attack requires a client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.

**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. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.
