There are remotely and easily exploitable vulnerabilities in the BlackBerry Enterprise Server that could allow an attacker to gain access to the server by simply sending a malicious image file to a user's BlackBerry device.

The vulnerabilities are in several version of BES for Exchange, Lotus Domino and Novell GroupWise, and Research in Motion said that an attacker who is able to exploit one of the bugs might also be able to move from the compromised BES server to other parts of the network. The company has issued a patch for the BES flaws and says that they are at the top of the severity scale in terms of exploitability.

The vulnerability in both the BlackBerry MDS Connection Service and the BlackBerry Messaging Agent is related to the way that the components handle PNG and TIFF image files. Exploiting the vulnerabilities can be as easy as sending a malicious PNG or TIFF file to a BlackBerry user. In some scenarios, the user wouldn't even need to open the email or click on a link in order to complete the attack.
