Microsoft (NSDQ:
MSFT) is planning to release an
out-of-band patch for Internet Explorer on Wednesday to address a critical security
vulnerability that is being actively exploited.
The company on Saturday warned that 1 in 500 Internet Explorer users worldwide may have been exposed to
malware hosted at both legitimate Web sites and porn sites that
exploit an unpatched vulnerability.
Microsoft confirmed finding exploit code on a
search engine in Taiwan and on a
Web site in Hong Kong that serves adult entertainment content.
"Based on our stats, since the vulnerability has gone public, roughly 0.2% of users worldwide may have been exposed to websites containing exploits of this latest vulnerability," Microsoft Security Response Center researchers Ziv Mador and Tareq Saade said in a
blog post. "That percentage may seem low, however it still means that a significant number of users have been affected. The trend for now is going upwards: We saw an increase of over 50% in the number of reports today compared to yesterday."
