CVE-2013-6476

First published: Thu Nov 07 2013(Updated: )

It was found that the OPVPWrapper::loadDriver() function in the pdftoopvp filter did not restrict the directory drivers could be loaded from. As the driver name can be configured based on a PPD file, processing a PDF in an attacker-controlled directory containing a malicious driver could lead to arbitrary code execution with the privileges of the "lp" user. Acknowledgements: This issue was discovered by Florian Weimer of the Red Hat Product Security Team.
