BlackBerry just pushed out new versions of BlackBerry Link for Windows and Mac. The update coincides with a new security vulnerability published by BlackBerry that has a remote possibility of being exploited. It was interesting to learn that the remote access from your BlackBerry 10 device to your desktop using Blackberry Link works over the industry standard WebDAV protocol.
You can read all about the potential exploit here though these are only potential vulnerabilities that are not being exploited in the wild. The three possible attack vectors all require either a user to click a malicious link or have access as a different user on your machine for it to be exploited.
