Users are urged to download and install a software patch from Microsoft.

Malicious code that can take advantage of a newly disclosed hole in Microsoft's MSN Messenger instant messenger program has been published on the Internet. The publication of the code could set the stage for a possibly virulent IM worm or virus, according to security experts.

The code attacks a hole in an MSN Messenger component called "libpng," which is used to display PNG (Portable Network Graphics) files that are used to show smiley faces, buddy icons, and other graphics. More than one example of code to exploit the hole was available on the Internet Wednesday, along with directions on how to use it to attack vulnerable Messenger applications. The code can cause Messenger to crash, or allow a remote attacker to run code on vulnerable Windows machines, according to a Vulnerability Alert released by Symantec.

Patch Available
On Tuesday, Microsoft released a patch, MS05-009, that fixed several holes in libpng for the PNG hole and labeled the vulnerability "critical."
