[HIGH] Microsoft Patch Tuesday, November 2025 Edition
Microsoft this week pushed security updates to fix more than 60 vulnerabilities in its Windows operating systems and supported software, including at least one zero-day bug that is already being exploited. Microsoft also fixed a glitch that prevented some Windows 10 users from taking advantage of an extra year of security updates, which is nice because the zero-day flaw and other critical weaknesses affect all versions of Windows, including Windows 10.
Affected products this month include the Windows OS, Office, SharePoint, SQL Server, Visual Studio, GitHub Copilot, and Azure Monitor Agent. The zero-day threat concerns a memory corruption bug deep in the Windows innards called CVE-2025-62215. Despite the flaw’s zero-day status, Microsoft has assigned it an “important” rating rather than c

CVE-2025-9242 [CRITICAL] CISA warns of WatchGuard firewall flaw exploited in attacks
## CISA warns of WatchGuard firewall flaw exploited in attacks
## Sergiu Gatlan
The U.S. Cybersecurity & Infrastructure Security Agency (CISA) has warned government agencies to patch an actively exploited vulnerability impacting WatchGuard Firebox firewalls.
Remote attackers can use this critical security flaw ( CVE-2025-9242 ) to execute malicious code remotely on vulnerable devices by exploiting an out-of-bounds write weakness in firewalls running Fireware OS 11.x (end of life), 12.x, and 2025.1.
CISA has added the vulnerability to its Known Exploited Vulnerabilities (KEV) catalog and has given Federal Civilian Executive Branch (FCEB) agencies three weeks, until December 3, to secure their systems against ongoing attacks as mandated by the Binding Operational Directive (BOD) 22-01.
