Microsoft November 2026 Security Updates Break Printing for Complex Documents

Microsoft has warned that its November 2026 security updates are causing printing failures on both server and client Windows systems. The issue occurs when documents contain images rendered with a height or width value of zero at the selected printing resolution. These zero-dimension images are commonly used for invisible watermarks, layout anchoring, or by generation tools that insert placeholder graphics. The problem primarily affects Microsoft Word documents printed through the Windows Graphics Device Interface but can impact other applications as well. Microsoft stated it is investigating the regression and will release additional guidance when available. This marks the latest in a series of printing-related problems introduced by recent cumulative updates, including issues from March and July 2025 as well as August 2026 .NET Framework patches.

Microsoft warned customers earlier this week that the November 2026 security updates may break printing for documents with complex formatting. As the company explained in a service alert, this known issue affects users attempting to print documents with images that have zero height or width on server (Windows Server 2016 or later) and client (Windows 10 or later) devices.

"After installing the November 2026 Windows security update, or later updates, printing might fail for documents containing images rendered with a height or width value of zero at the selected printing resolution," Microsoft said. "These images can be used as part of certain complex document formatting, such as adding 'invisible' images intended to serve as a document watermark, layout anchoring, or generation tools that may insert image objects even when no graphic is present."

The bug mainly affects users printing Microsoft Word documents via the Windows Graphics Device Interface (GDI), but it may also trigger failures when printing from other applications. "We are investigating this issue and will provide more information when it is available," the company added.

Previous Windows printing issues

Microsoft also addressed printing issues triggered by Windows updates in March and July 2025: the first caused USB printers to print random text, and the second broke the 'Print to PDF' feature. More recently, the company notified customers that the August 2026 .NET Framework cumulative updates broke printing and PDF export in apps that use the Windows Presentation Foundation (WPF) UI framework.

This week, Microsoft also confirmed that this month's Patch Tuesday security updates trigger Windows activation and licensing failures with 0x80041008 error codes and that Windows updates released since the October Patch Tuesday cause SQL Server performance and stability issues. Additionally, the company warned that the November 2026 Windows 11 security updates fail to install on systems with the October 2026 preview update.

Check Point Releases Emergency Hotfixes for Zero-Day CVE-2026-123039 Exploited for Root Access

Check Point has issued emergency hotfixes to address a high-severity local privilege escalation vulnerability tracked as CVE-2026-123039. The flaw resides in the DynamicCLI IPC interface of Gaia OS and has been actively exploited since late October to obtain root privileges and maintain persistence on affected devices. Attackers first compromised the Mobile Access portal via the PHP2Shell vulnerability before chaining it with CVE-2026-123039 to escalate privileges. They then deployed webshells, the TSGA backdoor, and TSProxy malware previously linked to Ivanti appliance attacks, pivoted to VMware ESXi hosts, and installed destructive wiper malware. Check Point observed the exploit targeting several dozen customers across its Firewall, Security Gateway, and Security Management Server products. Temporary mitigation involves stopping the dynamic_server process, while indicators of compromise include unusual system() sink usage and non-Clish commands. This marks the third zero-day campaign against Check Point products in recent months, following earlier exploitation of CVE-2026-93616 and CVE-2026-85102.

Citrix Patches Nine Critical NetScaler ADC and Gateway Flaws Plus One in Console

Citrix has released patches addressing 28 vulnerabilities across NetScaler ADC, NetScaler Gateway, and NetScaler Console. Nine of the issues in ADC and Gateway are rated critical and originate from memory overflow conditions in Packet Processing, SMPP traffic, DNS and DNS-over-HTTPS, NetScaler Push, Email OTP authentication, Endpoint Analysis, and ICA proxy. These flaws can trigger unpredictable behavior or denial-of-service conditions. A separate critical vulnerability in NetScaler Console, tracked as CVE-2026-120869 with a CVSS score of 9.4, allows unauthenticated attackers to bypass access controls. The remaining defects are mostly high-severity and affect similar functionality. Patches are available for NetScaler ADC and Gateway versions 14.1-73.57 and later, 13.1-64.39 and later, plus corresponding FIPS and NDcPP builds. Citrix recommends immediate updates and has disclosed precondition details for several of the issues.
