According to the official Ubisoft forums, the developers of Rainbow Six Vegas are hard at work and creating a patch for the game. Several bugs are being fixed, including single player voice recognition problems, exploits, voice chat online, display errors, Xbox Live Vision Camera crashes, and a few Spanish errors.

A post following the patch notes read:

Many of these issues were reported by members of the community, thanks to everyone that took the time to communicate with us. Please understand that this first patch was being worked on a few weeks ago already and that some of the recently discovered issues may not be addressed right away. We do know about these critical issues and are planning to address them as well.
