| Detailed Description |
The Hotfix (MS15-112, 3104517) for 'Security Update for Internet Explorer' has not been applied.
This security update resolves vulnerabilities in Internet Explorer. The most severe of the vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. 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 those who operate with administrative user rights.
Multiple Internet Explorer Memory Corruption Vulnerabilities
Multiple remote code execution vulnerabilities exist when Internet Explorer improperly accesses objects in memory. These vulnerabilities could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user.
Scripting Engine Memory Corruption Vulnerability - CVE-2015-6089
A remote code execution vulnerability exists in the way that the JScript and VBScript engines render when handling objects in memory in Internet Explorer. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the IE rendering engine. The attacker could also take advantage of compromised websites, and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability.
Internet Explorer Information Disclosure Vulnerability - CVE-2015-6086
An information disclosure vulnerability exists when Internet Explorer improperly discloses the contents of its memory. An attacker who successfully exploited this vulnerability could provide the attacker with information to further compromise the user's system.
Microsoft Browser ASLR Bypass - CVE-2015-6088
A security feature bypass exists when Internet Explorer fails to use the Address Space Layout Randomization (ASLR) security feature, allowing an attacker to more reliably predict the memory offsets of specific instructions in a given call stack. An attacker who successfully exploited it could bypass the Address Space Layout Randomization (ASLR) security feature, which helps protect users from a broad class of vulnerabilities. The security feature bypass by itself does not allow arbitrary code execution. However, an attacker could use this ASLR bypass in conjunction with another vulnerability, such as a remote code execution vulnerability, to more reliably run arbitrary code on a target system.
* Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of this condition will result in the check not being performed and a False Negative for all vulnerable hosts.
