## Microsoft Patch Tuesday for December 2025 — Snort rules and prominent vulnerabilities
The Patch Tuesday for December of 2025 includes 57 vulnerabilities, including two that Microsoft marked as “critical.” The remaining vulnerabilities listed are classified as “important.” Microsoft assessed that exploitation of the two “critical” vulnerabilities is “less likely.”
CVE‑2025‑62562 is a Microsoft Outlook remote code execution vulnerability. Although it involves a use after free in Microsoft Office Outlook to allow an unauthorized attacker to execute code locally, an attacker would still need to send a malicious email and persuade the user to reply to it for the exploit to work.
CVE-2025-62553 , CVE-2025-62554 , CVE-2025-62556 and CVE-2025-62557 are Microsoft Office Remote Code Execution
