Internet Explorer 0day: CVE-2014-1776

Posted April 29, 2014    BeyondTrust Research Team

Over the weekend, on April 26, Microsoft released an advisory about an Internet Explorer use-after-free zeroday vulnerability, CVE-2014-1776, that is being exploited in the wild. The vulnerability lies within MSHTML.dll, and affects Internet Explorer 6 through 11. According to FireEye, attacks have been spotted in the wild targeting Internet Explorer 9 through 11. The observed attacks rely on an exploit for Adobe Flash, which targets a now patched vulnerability, CVE-2014-0515. Exploiting the Flash vulnerability allowed attackers to bypass ASLR and DEP (security protection mechanisms).

Microsoft has released an out-of-band patch to address this vulnerability, MS14-021. Install this patch as soon as possible to address this vulnerability.

To mitigate this vulnerability, users are encouraged to apply the following workarounds until the patch can be applied.

• Configure EMET 4.1 or 5.0 to protect Internet Explorer. This was observed to mitigate exploitation of this vulnerability.
• Use Enhanced Protected Mode in IE (available in 10 and higher).
• Upgrade the Flash browser plugin to 13.0.0.206 for Windows/Mac and 11.2.202.356 for Linux.
• If you are unable to upgrade Flash, then disable the Flash browser plugin.
