<< Back VID 26777 Severity 40 Port 139,445 Protocol TCP Class SMB Detailed Description The Hotfix (MS16-085, 3169999) for 'Cumulative Security Update for Microsoft Edge' has not been applied. This security update resolves vulnerabilities in Microsoft Edge. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Microsoft Edge. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than users with administrative user rights. Microsoft Edge Security Feature Bypass A security feature bypass exists when Microsoft Edge does not properly implement Address Space Layout Randomization (ASLR). The vulnerability could allow an attacker to bypass the ASLR security feature, after which the attacker could load additional malicious code in the process in an attempt to exploit another vulnerability. Multiple Edge Memory Corruption Vulnerabilities Multiple remote code execution vulnerabilities exist when Microsoft Edge improperly accesses objects in memory. The vulnerabilities could corrupt memory in such a way that enables an attacker to execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Multiple Scripting Engine Memory Corruption Vulnerabilities Multiple remote code execution vulnerabilities exist in the way that the Chakra JavaScript engine renders when handling objects in memory in Microsoft Edge. The vulnerabilities could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerabilities could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Scripting Engine Information Disclosure Vulnerability An information disclosure vulnerability exists when VBScript improperly discloses the contents of its memory, which could provide an attacker with information to further compromise the user¡¯s computer or data. Microsoft Browser Information Disclosure Vulnerability An information disclosure vulnerability exists when the Microsoft Browser XSS Filter does not properly validate content under specific conditions. An attacker who exploited the vulnerability could run arbitrary JavaScript that could lead to an information disclosure. Microsoft Browser Spoofing Vulnerability A spoofing vulnerability exists when a Microsoft browser does not properly parse HTTP content. An attacker who successfully exploited this vulnerability could trick a user by redirecting the user to a specially crafted website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. Microsoft Browser Spoofing Vulnerability A spoofing vulnerability exists when the Microsoft Browser in reader mode does not properly parse HTML content. An attacker who successfully exploited this vulnerability could trick a user by redirecting them to a specially crafted website. The specially crafted website could spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. Microsoft Browser Information Disclosure Vulnerability An information disclosure vulnerability exists when the Microsoft Browser improperly handles objects in memory. An attacker who successfully exploited this vulne Recommendation Apply the appropriate patch(3169999) for your system, as listed in Microsoft Security Bulletin MS16-085 at https://technet.microsoft.com/en-us/library/security/ms16-085 -- OR -- Patches for Windows platforms are also available from the Microsoft Windows Update Web site, http://windowsupdate.microsoft.com. Windows Update detects what version of Windows you are running and offers the appropriate patch.
