BlackBerry Enterprise Server < 4.1.6 PDF Processing Arbitrary Code Execution

Medium

Synopsis

The remote Windows host has an application that is affected by a code execution vulnerability

Description

The version of BlackBerry Enterprise Server on the remote host reportedly contains a vulnerability in the PDF distiller component of the BlackBerry Attachment Service. A remote attacker may be able to leverage this issue to execute arbitrary code on the affected host subject to the privileges under which the application runs, generally 'Administrator', by sending an email message with a specially crafted PDF file and having that opened for viewing on a BlackBerry smartphone.

Solution

Either upgrade to BlackBerry Enterprise Server software version 4.1 Service Pack 6 (4.1.6), apply an appropriate interim security software update, or prevent the BlackBerry Attachment Service from processing PDF files.
