Due to some serious flaws in BlackBerry Enterprise Server and BlackBerry Unite software, Research In Motion has released a security update to correct these flaws.
The flaws can allow exploitation to execute auditory code and gain access to critical data. RIM said the multiple flaws exist in the PDF distiller of some of the BlackBerry Attachment Service; PDF distiller turns PostScript files into PDF docs.
Apparently an attacker can exploit these flaws via sending an email incorporating a malicious PDF file and if opened on a BlackBerry, the malicious code may cause memory corruption and “lead to arbitrary code execution on the computer that hosts the BlackBerry Attachment Service.”
