Microsoft Patch Tuesday July 2025

Microsoft’s July Patch Tuesday: A Massive Security Update with 140 Vulnerabilities

Microsoft has just released a huge security update as part of its monthly Patch Tuesday, addressing a staggering 130 CVEs (Common Vulnerabilities and Exposures)—including 10 critical bugs. Some of these vulnerabilities are so severe that hackers could take over your system without any user interaction.

In this post, we’ll break down the biggest threats and explain why you should install these updates immediately.

Why Is This Patch Tuesday So Big?

This month’s Patch Tuesday is one of the largest in recent memory, with 130 Microsoft vulnerabilities and an additional 10 third-party flaws, bringing the total to 140 CVEs. Among these, 10 are rated critical, and one is already publicly known, meaning hackers may already be exploiting it—or will soon.

What’s Causing the Surge?

  • Microsoft may be rushing fixes ahead of major hacker conferences.
  • It could simply be a coincidence—security flaws often come in waves.

Regardless of the reason, one thing is certain: You need to install these patches as soon as possible to protect your system.

The Most Dangerous Vulnerabilities

1. SPNEGO Extended Negotiation (NEGOEX) Remote Code Execution (CVE-2024-38060)

  • Impact: A wormable heap-based buffer overflow in Windows’ SPNEGO Extended Negotiation component.
  • Risk: Attackers can execute malicious code remotely by sending a specially crafted message—no user interaction required.
  • Severity: Microsoft rates this with its highest exploitability index, meaning attacks are expected within 30 days.

🔴 Action Required: Patch immediately—this is a prime target for hackers.

2. Microsoft SQL Server Remote Code Execution (CVE-2024-38053)

  • Impact: A heap-based buffer overflow in SQL Server allows attackers to run malicious queries and potentially escape the SQL Server context to execute code on the host machine.
  • Risk: If you run custom or third-party apps on SQL Server, you must update to OLEDB Driver 18 or 19.

🔴 Action Required: Check your SQL Server installations and apply updates.

3. Microsoft SharePoint Remote Code Execution (CVE-2024-38023)

  • Origin: Discovered at PWN2OWN Berlin, where security researchers exploited it to win $100,000 in Microsoft’s bug bounty program.
  • Risk: Allows code injection over the network. While it requires authentication, hackers can bypass this by chaining it with other exploits.

🔴 Action Required: Patch SharePoint servers immediately.

4. Microsoft Office Preview Pane Exploit (Multiple CVEs)

  • Impact: Four critical Office vulnerabilities allow malicious code execution just by previewing a file—no need to open it.
  • Trend: This is the third consecutive month with critical Office bugs.
  • Affected Versions:
    • Unsupported: Office versions before 2016 (no longer patched).
    • Ending Soon: Office 2016 reaches end-of-support on October 14, 2025 (same as Windows 10).
    • Mac Users: Updates for Office LTSC 2021/2024 aren’t yet available—consider disabling the preview pane.

🔴 Action Required: Update to Office 365 or Office 2024 and disable the preview pane if necessary.

How to Install the Updates

  1. Open Windows Update:
    • Windows 10/11: Click Start → Settings (Gear Icon) → Windows Update.
  2. Check for Updates:
    • If updates are pending, install them immediately.
  3. Restart Your PC:
    • Some patches require a reboot to take effect.

Why Speed Matters

  • One of these flaws is already public, meaning active attacks could be underway.
  • Microsoft expects exploits within 30 days for the most severe bugs.
