OVERVIEW:

       Multiple security vulnerabilities have been identified in some 
       versions of BlackBerry Enterprise Server.


IMPACT:

       The vendor has provided the following information regarding these
       vulnerabilities:

       "Multiple security vulnerabilities exist in the PDF distiller of 
       some released versions of the BlackBerry Attachment Service. These 
       vulnerabilities could enable a malicious individual to send an email 
       message containing a specially crafted PDF file, which when opened 
       for viewing on a BlackBerry smartphone, could cause memory corruption 
       and possibly lead to arbitrary code execution on the computer that 
       hosts the BlackBerry Attachment Service." [1]


MITIGATION:

       Updates are available for BlackBerry Enterprise Server software 
       version 5.0 [2], BlackBerry Enterprise Server software version
       4.1.x, and BlackBerry Professional Software [2, 3].
