RIM warns BlackBerry admins of critical unpatched PDF bug

Company posts workaround instructions for enterprise administrators.

Research in Motion has warned users and corporate administrators of a critical vulnerability in a component of its BlackBerry Enterprise Server that could be used to hack their company's computers.

The US Computer Emergency Readiness Team (US-CERT), part of the Department of Homeland Security, also posted an alert Wednesday after RIM issued two security advisories.

A patch is not available, but RIM said the problem had been "escalated internally to our development team."

A bug in the PDF distiller component of the BlackBerry Attachment Service, which runs on the BlackBerry Enterprise Server (BES), affects how the popular Adobe document format is processed on the server, said RIM in one of the advisories.

The server running BES, not individual BlackBerry devices, is at risk, although an attack would involve a BlackBerry.

Malicious PDFs attached to e-mail messages could "cause arbitrary code to execute on the computer that the BlackBerry Attachment Service runs on," the RIM warning said. "If a BlackBerry smart phone user on a BlackBerry Enterprise Server opens and views the specially crafted PDF file attachment on the BlackBerry smart phone, the arbitrary code execution could compromise the computer."

RIM posted workaround instructions for enterprise administrators that would prevent an attack by blocking PDF processing on a BES system.

A companion RIM security advisory urged BlackBerry users to upgrade to version 1.0 Service Pack 1 (1.0.1) bundle 36 or later of the BlackBerry Unite software.

Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.

It really doesn’t get more “gaming laptop” than this.

MSI GS75

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
