A flaw was found in the libpcap library. When remote packet capture support is enabled, it is possible to trigger a NULL pointer dereference when a filesystem path that is not a directory is used as an argument to the pcap_findalldevs_ex function due to a missing check of the return value from the opendir function, resulting in a denial of service.
