As a member of the Microsoft Active Protection Program (MAPP) New Window, Juniper Networks provides its customers with updated software protection information to address vulnerability exposures issued by Microsoft Security Advisory.



Microsoft Security Advisory (2847140): Vulnerability in Internet Explorer Could Allow Remote Code Execution

Microsoft is investigating public reports of a vulnerability in Internet Explorer 8. Microsoft is aware of attacks that attempt to exploit this vulnerability.

Internet Explorer 6, Internet Explorer 7, Internet Explorer 9, and Internet Explorer 10 are not affected by the vulnerability.

This is a remote code execution vulnerability. The vulnerability exists in the way that Internet Explorer accesses an object in memory that has been deleted or has not been properly allocated. The vulnerability may corrupt memory in a way that could allow an attacker to execute arbitrary code in the context of the current user within Internet Explorer. An attacker could host a specially crafted website that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the website.

Juniper Networks protects against this vulnerability with the following signature:

HTTP: Microsoft Internet Explorer Object Memory Use After Free

Released May 7, 2013
This signature detects attempts to exploit a known vulnerability against Microsoft Internet Explorer. A successful attack can lead to arbitrary code execution.

MICROSOFT SECURITY ADVISORY (2719615): VULNERABILITY IN MICROSOFT XML CORE SERVICES COULD ALLOW REMOTE CODE EXECUTION

Microsoft is aware of active attacks that leverage a vulnerability in Microsoft XML Core Services 3.0, 4.0, 5.0, and 6.0. The vulnerability could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker would have no way to force users to visit such a website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website. The vulnerability affects all supported releases of Microsoft Windows, and all supported editions of Microsoft Office 2003 and Microsoft Office 2007.

Juniper Networks protects against this vulnerability with the following signature:

HTTP: Microsoft Internet Explorer XML Remote Command Execution
Released June 12, 2012
This signature detects attempts to use unsafe ActiveX controls in XML Core Services. An attacker can create a malicious Web site containing Web pages with dangerous ActiveX controls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser.
