Detailed Description
Microsoft has released a cumulative security update for Internet Explorer (IE) to address eleven reported vulnerabilities. Ten of those are remote code execution vulnerabilities that existed when attempting to access a deleted object in memory, while the other one is an information disclosure vulnerability that was caused by a flaw in allowing VBScript to read JSON data files.
All of the vulnerabilities have been patched in the latest security update by modifying the way IE handles objects in memory and the way IE authorizes script access to data. Users are recommended to install the latest update to their system as a protection measure against possible exploit attempts.
