Active attacks exploiting zero-day bug were underway against IE6, IE7, and patch addresses other vulnerabilities in IE8
Microsoft today released an emergency, or out-of-band, patch for 10 vulnerabilities in Internet Explorer.

"The Internet Explorer team accelerated testing of this update due to the growing attacks against the publicly disclosed vulnerability (CVE-2010-0806), and the update has reached the appropriate quality bar for distribution to customers," said Microsoft Security Response group manager Jerry Bryant in a blog post. "Releasing the update early provides Internet Explorer 6 and 7 customers protection against the active attacks and provides users of all versions of Internet Explorer protection against nine other vulnerabilities."

Symantec security researcher Joshua Talbot said in an e-mail that the catalyst for the patch is the increased activity related to the iepeers.dll zero-day vulnerability that surfaced March 9. "Symantec has also observed a recent spike in attempted infections via this security hole," he said. "The typical attempted infection process seems to involve compromising a legitimate Web site then inserting an iframe which redirects users to a malicious site."   [More...] [Comments...]
