CVE/CAN name
Vendor threat level Critical
SophosLabs threat level High
Solution MS14-010
Vendor description This security update resolves one publicly disclosed vulnerability and twenty-three privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited the most severe of 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 As these vulnerabilities have a major impact on Internet Explorer (default browser on all Windows operating systems), SophosLabs actively encourages users to apply this patch as soon as it is available.
