Research in Motion has issued a security bulletin outlining a security threat on the BlackBerry Enterprise Server 4.1 Service Pack 3 (4.1.3) through 4.1 Service Pack 5 (4.1.5). The bug may let an attacker send hostile code hidden in a PDF file. When opened on a Blackberry smart phone, the bad code will run. Fix this by upgrading to Enterprise Server software version 4.1 Service Pack 6 (4.1.6).
