| Detailed Description |
The Hotfix (MS12-052, 2722913) for 'Cumulative Security Update for Internet Explorer' has not been applied.
This security update resolves four privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the current user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
- Layout Memory Corruption Vulnerability (CVE-2012-1526)
A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted. The vulnerability may corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user.
- Asynchronous NULL Object Access Remote Code Execution Vulnerability (CVE-2012-2521)
A remote code execution vulnerability exists in the way that Internet Explorer accesses an object that has been deleted. The vulnerability may corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user.
- Virtual Function Table Corruption Remote Code Execution Vulnerability (CVE-2012-2522)
A remote code execution vulnerability exists in the way that Internet Explorer accesses a corrupted virtual function table that has been deleted. The vulnerability may corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user.
-JavaScript Integer Overflow Remote Code Execution Vulnerability (CVE-2012-2523)
A remote code execution vulnerability exists in the way that Internet Explorer calculates the size of an object in memory during a copy operation. The vulnerability may corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user.
* 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.
