| Vulnerability Description Multiple vulnerabilities have been reported in Adobe Reader and Acrobat when handling PDF files that contain a JBIG2 stream. A remote attacker can exploit this vulnerability to execute arbitrary code on an affected system via a specially crafted PDF file. Portable Document Format (PDF) is an open file format created by Adobe Systems. It is used for representing two-dimensional documents in a device and resolution independent fixed-layout document format. Successful exploitation of this issue will crash the vulnerable application, and may allow execution of arbitrary code on an affected system. |

Vulnerability Details There are multiple heap overflow vulnerabilities in the JBIG2 filter that could lead to code execution. The vulnerabilities are 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 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. |
