Who is Vulnerable?
Vulnerability Description	Portable Document Format (PDF) is a file format for documents based on the PostScript description language. One of the products that is widely used to read PDF files is Adobe Acrobat Reader. This product is available on different platforms, including many versions of UNIX and Linux. There is a vulnerability in the way Adobe Acrobat Reader validates a filename within the uudecode function. A specially crafted filename can allow an attacker to execute arbitrary programs with privileges equivalent to the user that opened the malicious PDF document. In the attack case, the vulnerable software will report that it was not able to open the PDF document that was sent to the victim. The attacker supplied code will then execute arbitrary commands on the target with the privileges of the victim. The behaviour of the target depends on the commands being executed.
