Exploit for critical vulnerability in Microsoft Office appears in the wild

An exploit has been discovered in the wild that can successfully attack a critical vulnerability in the way Microsoft Office handles Rich Text Format data, allowing remote execution of code on a victim computer. Microsoft released a patch for the vulnerability, known as CVE-2010-3333, in November 2010, and no widespread outbreaks of exploits have yet been reported. The public availability of an exploit lowers the bar for attackers, however, and increases the urgency for seeing that affected software is patched.
