Microsoft Patch Tuesday for June 2025 — Snort rules and prominent vulnerabilities

Microsoft's June 2025 security update fixes 66 vulnerabilities (including eleven critical entries) across Windows components and Microsoft Office/SharePoint, covering multiple RCEs (e.g., RDS, Schannel, KDC Proxy, Word, SharePoint) and critical elevation-of-privilege issues (Netlogon, Power Automate). Microsoft reports no widespread active exploitation, but several vulnerabilities have high CVSS scores and some are assessed as "more likely" to be exploited; Talos released Snort and Snort3 rules to detect exploitation attempts and recommends applying Microsoft updates and IDS rule updates promptly.
