BlackBerry has warned its enterprise users that it has found a serious problem with BlackBerry Enterprise Server, and a patch needs to be applied immediately.
The vulnerability is in BES components that process images. If a BlackBerry device gets a TIFF image file in an email -- just receives it, it doesn't need to be opened on the device -- then it's possible that a hacker could remotely gain access to and execute code on the BES server. The TIFF image could also be embedded on a webpage.
To remove this vulnerability, it is necessary to install either the newly-released BlackBerry Enterprise Server version 5.0.4 MR2, or the interim security update to BlackBerry Enterprise Server Express version 5.0.4.
