Memory corruption vulnerabilities have been discovered in the way multiple products handle specially crafted PDF files that contain malformed JBIG2 structures. Successful exploitation of this issue will allow execution of arbitrary code on an affected system. The vulnerabilities are due to the way multiple products handle malformed JBIG2 structures in PDF documents. A remote attacker could trigger this issue via a specially crafted PDF file.
