[Download now](/resources/complete-guide-to-data-breaches) Upon its release, Windows 7 was hailed as "the most secure Windows ever"—true enough at the time, but its predecessor Windows Vista didn't exactly set a high bar security-wise.  Nonetheless, the updated OS shipped with literally hundreds of security changes and additions, addressing the needs of a more security-conscious home and business user base with features like AppLocker, BitLocker Drive [Encryption](/blog/encryption) technology, and more. Despite these improvements, Windows 7 has its own set of critical vulnerabilities—here are the top 10 on the list and how to fix them. ## 10 Critical Windows 7 Vulnerabilities ### 10. Driver Improper Interaction with Windows Kernel Vulnerability [***CVE-2010-4398***](https://www.cvedetails.com/cve/CVE-2010-4398/) By using a stack-based buffer overflow in the RtlQueryRegistryValues function in win32k.sys, local users can gain privileges and bypass the User Account Control (UAC) feature through a specially crafted REG\_BINARY value for a SystemDefaultEUDCFont registry key.  ### 9. Windows Fax Services Cover Page Editor Vulnerability [***CVE-2010-4701***](https://www.cvedetails.com/cve/CVE-2013-0008/) If you're still faxing, here's another reason to leave that remnant of the 80's behind: a heap-based buffer overflow in the CDrawPoly::Serialize function in fxscover.exe in Microsoft [Windows](/blog/top-10-ways-to-secure-your-windows-environment) Fax Services Cover Page Editor 5.2 r2 could allow remote attackers to execute arbitrary code via a long record in a Fax Cover Page (.cov) file.  ### 8. Win32k Improper Message Handling Vulnerability [***CVE-2013-0008***](https://www.cvedetails.com/cve/CVE-2013-0008/) Another kernel-mode [vulnerability](/blog/vulnerability), this flaw also involves win32k.sys in the kernel-mode drivers. In this case, they do not properly handle window broadcast messages and could potentially allow local users to gain privileges through a specially crafted application. ### 7. Win32k.sys Elevation of Privilege Vulnerability [***CVE-2014-4113***](https://www.cvedetails.com/cve/CVE-2014-4113/) Windows 7's win32k.sys in kernel-mode drivers could enable local users to gain privileges through a specially crafted application. ### 6. Win32k Window Class Vulnerability [***CVE-2010-2744***](https://www.cvedetails.com/cve/CVE-2010-2744/) Windows 7's kernel-mode drivers improperly manage a window class, thereby allowing local users to gain privileges by creating a window and then (1) the SetWindowLongPtr function to modify the popup menu structure, or (2) the SwitchWndProc function with a switch window information pointer, which is not re-initialized when a WM\_NCCREATE message is processed. ### 5. Windows MFC Document Title Updating Buffer Overflow Vulnerability [***CVE-2010-3227***](https://www.cvedetails.com/cve/CVE-2010-3227/) This vulnerability involves the potential for stack-based buffer overflows in the UpdateFrameTitleForDocument method in the CFrameWnd class in mfc42.dll in the Microsoft Foundation Class (MFC) Library. Exploitation by attackers involves arbitrary code executed by way of a long window title, created at the request of the application by the library. ### 4. GDI Access Violation Vulnerability [***CVE-2011-5046***](https://www.cvedetails.com/cve/CVE-2011-5046/) Primarily a Windows API for displaying graphics, the Graphics Device Interface (GDI) in win32k.sys in the kernel-mode drivers do not properly validate user-mode input. This could give remote attackers the ability to execute arbitrary code or cause a memory corruption denial of service (DoS) with specially crafted data. ### 3. Windows OLE Remote Code Execution Vulnerability [***CVE-2014-4114***](https://www.cvedetails.com/cve/CVE-2014-4114/) Back in 2014, the so-called Sandworm made security headlines with its use of malicious Powerpoint files to install malware. Vulnerable Windows 7 installations could allow remote attackers to execute arbitrary code with a specially crafted OLE object in an Office document. ### 2. Insecure Library Loading Vulnerability [***CVE-2010-3147***](https://www.cvedetails.com/cve/CVE-2010-3147/) Windows Address Book (WAB) is a component that allows users to use a single list of contacts shared across multiple applications. Unfortunately, an untrusted search path vulnerability in wab.exe 6.00.2900.5512 in WAB could allow a local attacker to gain privileges via a Trojan horse wab32res.dll file in the current working directory. ### 1. Directory Traversal Elevation of Privilege Vulnerability [***CVE-2015-0016***](https://www.cvedetails.com/cve/CVE-2015-0016/) This directory traversal vulnerability in the Terminal Services component TSWbPrxy could allow a remote attacker to gain privileges with a specially crafted pathname in an executable file. Microsoft ended mainstream support for Windows 7 back in January 2015, but as of this writing Windows 7 continues to command over 55% of the desktop OS market share.
