Internet Explorer vuln advisory

The following cyber advisory was issued by the New York State Office of Cyber Security (OCS) and is intended for State government entities. The information may or may not be applicable to the general public and accordingly, the State does not warrant its use for any specific purposes. OCS ADVISORY NUMBER: 2012-044 DATE(S) ISSUED: 06/12/2012 SUBJECT: Cumulative Security Update for Internet Explorer (MS12-037) OVERVIEW: Multiple vulnerabilities have been discovered in Microsoft's web browser, Internet Explorer, which could allow an attacker to take complete control of an affected system. Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. SYSTEMS AFFECTED: • Internet Explorer 6 • Internet Explorer 7 • Internet Explorer 8 • Internet Explorer 9 RISK: Government: • Large and medium government entities: High • Small government entities: High Businesses: • Large and medium business entities: High • Small business entities: High Home users: High DESCRIPTION: Thirteen vulnerabilities have been discovered in Microsoft Internet Explorer. Details of these vulnerabilities are as follows: Remote Code Execution Vulnerabilities: Nine remote code execution vulnerabilities have been discovered in Internet Explorer. These are memory corruption vulnerabilities that occur due to the way Internet Explorer accesses objects in memory that have not been properly deleted. These vulnerabilities may be exploited if a user visits a web page that is specifically crafted to take advantage of the vulnerabilities. Successful exploitation of any of these vulnerabilities could result in an attacker taking complete control of the system. Information Disclosure Vulnerabilities: Four information disclosure vulnerabilities have been discovered in Internet Explorer. These vulnerabilities could be exploited if an attacker convinces a user to visit a specially crafted website which would allow the attacker to access information in other domains or Internet Explorer Zones. RECOMMENDATIONS: We recommend the following actions be taken: • Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing. • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack. • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources. • Remind users not to open e-mail attachments from unknown users or suspicious e-mails from trusted sources.
