| Detailed Description |
The Hotfix (MS15-094, 3089548) 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 these 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 Memory Corruption Vulnerabilities in Internet Explorer
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-2015-2493
A remote code execution vulnerability exists in the way that the VBScript and JScript engines, when rendered in Internet Explorer, handle objects in memory. 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.
Elevation of Privilege Vulnerability - CVE-2015-2489
An elevation of privilege vulnerability exists when Internet Explorer does not properly validate permissions under specific conditions, potentially allowing a script to be run with elevated privileges.
Information Disclosure Vulnerability - CVE-2015-2483
An information disclosure vulnerability exists when Internet Explorer improperly discloses the contents of its memory, which could provide an attacker with information to further compromise the user's computer. The update addresses the vulnerability by changing the way certain functions handle objects in memory.
Tampering Vulnerability - CVE-2015-2484
A tampering vulnerability exists when Internet Explorer accesses a file with an improper flag that in turn permits a file operation. This could allow a low privilege process to delete arbitrary files on the local system. This update addresses the vulnerability by properly masking this flag off.
* 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.
