It is used for representing two-dimensional documents in a device and resolution independent fixed-layout document format.A buffer overflow vulnerability has been reported in Adobe Reader and Acrobat when handling PDF files that contain a JBIG2 stream.The vulnerability is due to errors in Adobe products that fail to sufficiently validate input when processing embedded JBIG2 streams within PDF documents. A remote attacker could trigger this flaw via a specially crafted PDF file. Successful exploitation allows execution of arbitrary code once a malicious PDF file is loaded on a vulnerable system and may cause the affected Acrobat application to crash.|
