BlackBerry Enterprise Server Security Flaw

RIM has just issues a security warning to admins regarding BlackBerry Enterprise Server. It seems that there is a serious security flaw with the BlackBerry Attachment Service and PDF files. RIM has even gone so far as to rate the severity as 9 out of a possible 10. Said flaw apparently allows the hackers to execute malicious code via a specially crafted PDF file. The flaw affects BES (BlackBerry Enterprise Server) versions 4.1 SP3 to 4.1 SP5. Fortunately RIM currently has a workaround which involves disabling the processing of PDF files, which should suffice until a permanent fix is found.
