RIM has issued a security update for users of BlackBerry Enterprise Server and BlackBerry Professional Software.
It has something do with PDF files once again. The advisory says that multiple security vulnerabilities exist in the PDF distiller of some released versions of the BlackBerry Attachment Service component of the BlackBerry Enterprise Server.
The 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 that is associated with a user account on a BlackBerry Enterprise Server, could cause memory corruption and possibly lead to arbitrary code execution on the computer that hosts the BlackBerry Attachment Service component of that BlackBerry Enterprise Server.
Research In Motion
(RIM) issued an interim security software update that resolves
these vulnerabilities in affected versions of the BlackBerry Enterprise
Server and BlackBerry Professional Software.
