eWeek-Security: Exploit Posted for New IE Zero-Day

Security researchers in China have published detailed exploit code for a new zero-day vulnerability in Microsoft’s dominant Internet Explorer browser.

The exploit, which was posted to XSec.org and Milw0rm.com Web sites, could be easily modified to launch code execution attacks without any user action on fully patched Windows machines.

A spokesman for the MSRC (Microsoft Security Response Center) said the company is investigating the latest warning, which adds to a list of known high-risk vulnerabilities that remain unpatched.
