Description Murray McAllister 2013-11-07 04:29:56 UTC
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.
