BlackBerry users face security threat CNET News.com: "Windows users know that opening a malicious e-mail attachment can wreak havoc on their PC. It appears BlackBerry users have to use caution too.
Opening a malicious image sent via an e-mail on the popular mobile devices could disable a user's capability to view attachments, BlackBerry maker Research In Motion said Tuesday.
The problem occurs because of a software flaw in the BlackBerry Enterprise Server, RIM said in a posting on its customer support Web site. An attacker would have to craft a special TIFF, or Tagged Image File Format, to perform the attack, the company said."
