Palo Alto Networks researcher Bo Qu has discovered 4 new critical Internet Explorer (IE) vulnerabilities covering versions 8, 9, 10, and the latest, Internet Explorer 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 MS14-010 and part of the February 2013 Security Bulletin.

Details:

  • Critical memory corruption vulnerability affecting Internet Explorer versions 8, 9 & 10 (CVE-2014-0272)

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.

Bo Qu’s recent published discoveries also include an IE vulnerability in December 2013, and three IE vulnerabilities in November 2013.
