CIO - BlackBerry-maker Research In Motion (RIM) yesterday issued a security fix to address yet another flaw in its BlackBerry Enterprise Server's (BES) BlackBerry Attachment Service, which processes message attachments for viewing on BlackBerry devices.
The problem: Flaws in the BES PDF distiller could allow attackers to distribute messages with malicious PDF files attached that, if opened via BlackBerry, could lead to device memory corruption and in turn, harmful code could be executed on corporate computers hosting the BES Blackberry Attachment Service.
This particular flaw is found in BES version 4.1 Service Pack 3 (4.1.3) through 5.0 and BlackBerry Professional Software 4.1 Service Pack 4 (4.1.4). The vulnerability is a critical one with a Common Vulnerability Scoring System (CVSS) rating of 9.3 out of 10, according to RIM.
Visit RIM's website for more specifics on the vulnerability, as well as a handful of potential workarounds to disable PDF viewing on enterprise BlackBerrys.
