Who is Vulnerable?
Vulnerability Description	Memory corruption vulnerabilities have been discovered in Apple CUPS and Cog Xpdf. 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. Successful exploitation will create a denial of service condition, causing the application to become non-responsive, and may allow execution of arbitrary code once a malicious PDF file is loaded on a vulnerable system.
