Qualys Vulnerability R&D Lab has released new vulnerability checks in the Qualys Cloud Platform to protect organizations against 8 vulnerabilities that were fixed in 1 bulletins announced today by Microsoft. Customers can immediately audit their networks for these and other new vulnerabilities by accessing their Qualys subscription. Visit our blog to see how to prioritize remediation.
Microsoft has released 1 security bulletins to fix newly discovered flaws in their software. Qualys has released the following checks for these new vulnerabilities:
Internet Explorer is prone to the following vulnerabilities:
An XSS filter bypass vulnerability exists in the way that Internet Explorer 8 disables an HTML attribute in otherwise appropriately filtered HTTP response data. The vulnerability could allow initially disabled scripts to run in the wrong security context, leading to information disclosure.(CVE-2009-4074).
A remote code execution vulnerability exists in the way that Internet Explorer incorrectly validates input. An attacker could exploit the vulnerability by constructing a specially crafted URL.An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user.(CVE-2010-0027).
Multiple remote code execution vulnerabilities exists in the way that Internet Explorer accesses an object that has not been correctly initialized or has been deleted. An attacker could exploit these vulnerabilities by constructing a specially crafted Web page. When a user views the Web page, the vulnerability could allow remote code execution.(CVE-2010-0244, CVE-2010-0245,CVE-2010-0246,CVE-2010-0247,CVE-2010-0248,CVE-2010-0249).
Microsoft has released a security update that addresses these vulnerabilities by modifying the way that Internet Explorer handles objects in memory, validates input parameters, and filters HTML attributes.
The security update is rated Critical for all supported releases of Internet Explorer: Internet Explorer 5.01, Internet Explorer 6, Internet Explorer 6 Service Pack 1, Internet Explorer 7, and Internet Explorer 8 (except Internet Explorer 6 for supported editions of Windows Server 2003). For Internet Explorer 6 for supported editions of Windows Server 2003 as listed, this update is rated Moderate.
