The version of Microsoft Malware Protection Engine (MMPE) installed on the remote Windows host is prior to 1.1.13804.0. It is, therefore, affected by multiple vulnerabilities :

  - Multiple denial of service vulnerabilities exist due to     improper scanning of specially crafted files. An     unauthenticated, remote attacker can exploit these, by     convincing a user to download or open a malicious file,     to cause the monitoring service to stop. (CVE-2017-8535,     CVE-2017-8536, CVE-2017-8537, CVE-2017-8539,     CVE-2017-8542)

  - Multiple memory corruption issues exist due to improper     validation of input when scanning specially crafted     files. An unauthenticated, remote attacker can exploit     these, by convincing a user to download or open a     malicious file, to cause a denial of service condition     or the possible execution of arbitrary code.
    (CVE-2017-8538, CVE-2017-8541)

  - A use-after-free error exists in the garbage collection     system used for managing JavaScript objects when     scanning specially crafted files. An unauthenticated,     remote attacker can exploit this, by convincing a user     to download or open a malicious file, to dereference     already freed memory and potentially execute arbitrary     code. (CVE-2017-8540)

  - A flaw exits in the x86 emulator implementation for the     Win32 API due to improper restrictions on access to     certain NTDLL routines. An unauthenticated, remote     attacker can exploit this, by convincing a user to     download or open a malicious file, to execute arbitrary     code with SYSTEM privileges.

Note that Nessus has checked if a vulnerable version of MMPE is being used by any of the following applications :

  - Microsoft Forefront Endpoint Protection 2010

  - Microsoft Endpoint Protection

  - Microsoft Forefront Security for SharePoint

  - Microsoft System Center Endpoint Protection

  - Microsoft Security Essentials

  - Windows Defender for Windows 7, Windows 8.1, Windows RT     8.1, Windows 10, Windows 10 1511, Windows 10 1607,     Windows 10 1703, and Windows Server 2016

  - Windows Intune Endpoint Protection

遠端 Windows 主機上安裝的 Microsoft Malware Protection Engine (MMPE) 版本比 1.1.13804.0 舊。因此，會受到多個弱點影響：- 存在多個拒絕服務弱點，這是因為不當掃描特製的檔案所致。未經驗證的遠端攻擊者可惡意利用這些弱點，誘騙使用者下載或開啟惡意檔案，造成監視服務停止。(CVE-2017-8535、CVE-2017-8536、CVE-2017-8537、CVE-2017-8539、CVE-2017-8542) - 多個記憶體損毀問題，這是因為在掃描特製的檔案時，不當驗證輸入所致。未經驗證的遠端攻擊者可惡意利用這些問題，透過誘騙使用者下載或開啟惡意檔案，引發拒絕服務情形或可能執行任意程式碼。(CVE-2017-8538、CVE-2017-8541) - 掃描特製檔案時用來管理 JavaScript 物件的記憶體回收系統中，存在一個釋放後使用錯誤。未經驗證的遠端攻擊者可惡意利用此錯誤，誘騙使用者下載或開啟惡意檔案，藉此解除參照已釋放的記憶體，且可能執行任意程式碼。(CVE-2017-8540) - Win32 API 的 x86 模擬器實作中存在一個缺陷，這是因為不當限制存取特定 NTDLL 常式所致。未經驗證的遠端攻擊者可惡意利用此缺陷，誘騙使用者下載或開啟惡意檔案，進而以 SYSTEM 權限執行任意程式碼。(VulnDB 158110) 請注意，Nessus 已檢查下列應用程式是否有使用容易遭受攻擊的 MMPE 版本：- Microsoft Forefront Endpoint Protection 2010 - Microsoft Endpoint Protection - Microsoft Forefront Security for SharePoint - Microsoft System Center Endpoint Protection - Microsoft Security Essentials - Windows 7、Windows 8.1、Windows RT 8.1、Windows 10、Windows 10 1511、Windows 10 1607、Windows 10 1703 和 Windows Server 2016 版的 Windows Defender - Windows Intune Endpoint Protection

远程 Windows 主机上安装的 Microsoft Malware Protection Engine (MMPE) 版本低于 1.1.13804.0。因而会受到多个漏洞的影响：- 由于未正确扫描特制的文件，存在多个拒绝服务漏洞。未经身份验证的远程攻击者可利用这些漏洞，诱使用户下载或打开恶意文件，从而造成监视服务停止。(CVE-2017-8535, CVE-2017-8536, CVE-2017-8537, CVE-2017-8539, CVE-2017-8542) - 由于扫描特制的文件时，未正确验证输入，存在多个内存损坏问题。未经身份验证的远程攻击者可利用这些问题，诱使用户下载或打开恶意文件，造成拒绝服务情况或可能的任意代码执行。(CVE-2017-8538, CVE-2017-8541) - 扫描特制的文件时，用于管理 JavaScript 对象的垃圾回收系统中存在释放后使用错误。未经身份验证的远程攻击者可利用此错误，诱使用户下载或打开恶意文件，取消引用已释放的内存并潜在执行任意代码。(CVE-2017-8540) - 由于不当限制对某些 NTDLL 例程的访问权，Win32 API 的 x86 仿真器实施中存在缺陷。未经身份验证的远程攻击者可利用此问题，诱使用户下载或打开恶意文件，以 SYSTEM 权限执行任意代码。请注意，Nessus 已检查下列任意应用程序是否在使用 MMPE 有漏洞的版本：- Microsoft Forefront Endpoint Protection 2010 - Microsoft Endpoint Protection - Microsoft Forefront Security for SharePoint - Microsoft System Center Endpoint Protection - Microsoft Security Essentials - Windows Defender for Windows 7, Windows 8.1, Windows RT 8.1, Windows 10, Windows 10 1511, Windows 10 1607, Windows 10 1703, and Windows Server 2016 - Windows Intune Endpoint Protection
