Security readout for executives and security teams

CVE-2013-6473 is a memory-safety flaw in the cups-filters urftopdf print filter. A specially large URF page or line could cause heap buffer overflows and potentially allow remote code execution on systems processing those files. Exposure is most likely on Linux printing systems running cups-filters 1.0.25 through versions before 1.0.47, especially where URF print data can be submitted by remote users or untrusted clients. Treat as high priority for systems that expose printing services to untrusted users. The absence of supplied exploitation evidence lowers emergency urgency, but remote code execution potential warrants timely remediation. Mitigation focus: Update cups-filters using vendor packages or to version 1.0.47 or later.; Review Ubuntu, Debian, Red Hat, and OpenPrinting guidance for distro-specific fixes.; Restrict print service access to trusted networks and users..
