Microsoft today issued security updates to fix at least 56 vulnerabilities in its Windows operating systems and supported software, including two zero-day flaws that are being actively exploited.

But there's plenty in it — including two zero-days — that need immediate attention.

Microsoft has released its monthly security update for January of 2025 which includes 58 vulnerabilities, including 3 that Microsoft marked as “critical” and one marked as "moderate". The remaining vulnerabilities listed are classified as “important.”

**According to the CVSS metric, successful exploitation of this vulnerability has a high impact on availability (A:H). What does that mean for this vulnerability?** An attacker can send specially crafted messages to the MSMQ service, which could affect availability of the service and result in Denial of Service (DoS).

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

**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.

**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.

**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.

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