The Firewall Tester consists of two perl scripts, the client part (ftest) and the listening sniffer (ftestd). The client injects custom marked packets, while the sniffer listens for them. The comparison of the script's log files permit the detection of filtered packets and consequently filtering rules if the two scripts are ran on different sides of a firewall. An IDS (Intrusion Detection System) testing feature is also available and snort rule definition file can parsed instead of the standard configuration syntax, ftest can also use common IDS evasion techniques. Stateful inspection firewall and IDS can be tested with the 'connection spoofing' option. Requires: Net::RawIP, Net::PcapUtils, NetPacket.

Red Hat Security Advisory RHSA-2003:006-06 - Unpatched versions of libpng 1.2.1 and earlier do not correctly calculate offsets, which leads to a buffer overflow and arbitrary code execution. This can be exploited by an attacker creating a carefully crafted PNG file which executes arbitrary code when the victim views it.
