Vendor description
|
This security update resolves three privately reported vulnerabilities in Internet Explorer. The vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited 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.

SophosLabs comments

When IE attempts to access an object that has been deleted, the IE process may corrupt memory enabling an attacker to execute arbitrary code in current user space.
