One of the service components inside BlackBerry Enterprise Server is the BlackBerry Attachment Service, which retrieves and converts attachments from Word, Excel, PowerPoint, WordPerfect, PDF, ASCII documents, HTML attachments, JPG, BMP, GIF, PNG and TIFF images and file types listed above archived in .zip format documents to the Universal Content Stream format for BlackBerry device. The specific component that handles PDF files is the PDF distiller, which could allow arbitrary code execution on the computer that hosts the BlackBerry Attachment Service due to buffer overflow errors.

PDF vulnerabilities have become very common and it is important that all those who have services with programs that depend on this format place additional controls to minimize the risk of malware and buffer overflows in the infrastructure.
