Who is Vulnerable?
Vulnerability Description	Portable Document Format (PDF) is an open file format created by Adobe Systems. Multiple vulnerabilities have been reported in Adobe Reader and Acrobat when handling PDF files that contain a JBIG2 stream. A remote attacker could trigger these flaws via a specially crafted PDF file. Successful exploitation will create a denial of service condition, causing the application to crash, and may allow execution of arbitrary code once a malicious PDF file is loaded on a vulnerable system. There are cases in which certain traffic, although not intended for malicious use, is very unsafe, since it may transfer shellcode which is undetectable by IPS.
