Summary
A cumulative security update for Internet Explorer has been released to address multiple reported vulnerabilities that could lead to cross-site scripting and remote code execution.
Detailed Description
Microsoft has released a cumulative security update for Internet Explorer (IE) to address multiple reported vulnerabilities. One of them is a cross-site scripting vulnerability that could lead to information disclosure. It was caused by an error in handling the encoding for Shift_JIS auto-selection, which allows the attacker to view content from different domains. The rest of the reported vulnerabilities, 16 in total, are all remote code execution vulnerabilities. They were caused by improper access of memory, resulting in memory corruption condition that could give ways for the attacker to execute code.
All of these issues have been resolved through the update by blocking cross-domain scrolling events in IE and by modifying the way of handling objects in memory. Users are recommended to install the latest update to protect their system from possible exploit attempts.
