Palo Alto Networks Discovers 3 Critical Internet Explorer Vulnerabilities

Palo Alto Networks researchers discovered 3 new critical Internet Explorer (IE) vulnerabilities covering IE versions 8, 9, 10 and 11.

Each of these discoveries allows full remote code execution using a memory corruption vulnerability in IE. They have been documented in Microsoft Security Bulletin MS14-051and part of the August 2014 Security Bulletin. Palo Alto Networks researcher Bo Qu is credited with all 3 vulnerabilities.

Palo Alto Networks customers are protected from these vulnerabilities through our regular Vulnerability Protection updates, and we recommend Internet Explorer users upgrade to the latest patch from Microsoft.

In our continuing commitment to the security research community, these vulnerabilities were disclosed to Microsoft through our participation in the Microsoft Active Protections Program (MAPP) program, which ensures the timely, responsible disclosure of new vulnerabilities and creation of protections from security vendors.

In the past six months, Palo Alto Networks has discovered many critical Internet Explorer vulnerabilities, including 10 in July 2014, 22 in June 2014 (revised from 21) and four in February 2014.

By proactively identifying these vulnerabilities, developing protections for our customers, and sharing them with Microsoft for patching, we are removing one weapon used by Advanced Persistent Threats to compromise enterprise networks.
