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. The update addresses the vulnerabilities by modifying the way that Internet Explorer handles objects in memory.
Multiple Elevation of Privilege Vulnerabilities in Internet Explorer
Elevation of privilege vulnerabilities exist when Internet Explorer does not properly validate permissions under specific conditions, potentially allowing script to be run with elevated privileges. The update addresses the vulnerabilities by adding additional permission validations to Internet Explorer.
Multiple Internet Explorer Cross-domain Information Disclosure Vulnerabilities
Information disclosure vulnerabilities exist when Internet Explorer does not properly enforce cross-domain policies, which could allow an attacker to gain access to information in another domain or Internet Explorer zone. The update addresses the vulnerabilities by helping to ensure cross-domain policies are properly enforced in Internet Explorer.
Internet Explorer Clipboard Information Disclosure Vulnerability
An information disclosure vulnerability exists when Internet Explorer does not properly restrict access to the clipboard of a user who visits a website. The vulnerability could allow data stored on the Windows clipboard to be accessed by a malicious site. An attacker could collect information from the clipboard of a user if that user visits the malicious site. The update addresses the vulnerability by helping to prevent information stored on a user’s clipboard from being accessed by a malicious site.
Internet Explorer ASLR Bypass Vulnerability
A security feature bypass vulnerability exists when Internet Explorer does not use the Address Space Layout Randomization (ASLR) security feature, which could allow an attacker to more reliably predict the memory offsets of specific instructions in a given call stack. The update addresses the vulnerability by helping to ensure that affected versions of Internet Explorer properly implement the ASLR security feature.
