Windows animated cursor flaw--150 sites infected

There's a new Microsoft Windows vulnerability being exploited across the Internet on over 150 Web sites. The vulnerability is caused by an unspecified error in the way Windows 2000, XP, and Vista handles animated cursors.

Animated cursors allow a mouse pointer to appear animated on a Web site. The feature is often designated by the .ani suffix, but attacks for this vulnerability are not constrained by this file type so simply blocking .ani files won't necessarily protect a PC. Successful exploitation can result in memory corruption when processing cursors, animated cursors, and icons. According to Arbor Networks, the malicious code on compromised Web sites exploiting this flaw appears to be originating from the following sites, which you may want to block:

To become infected, users must be using Internet Explorer 6 or 7; there is no need to click, just visiting an infected site is enough for an infection. The flaw does not affect Firefox or Opera Internet Browsers. Microsoft will release a patch on April 3, 2007. Until a patch is released, users should browse the Internet using a non-Internet Explorer browser.
