Darren Reed Ipfilter

IPFilter 3.4.16 and earlier does not include sufficient session information in its cache, which allows remote attackers to bypass access restrictions by sending fragmented packets to a restricted port after sending unfragmented packets to an unrestricted port.

IPFilter 3.1.1 through 3.4.28 allows remote attackers to bypass firewall rules by sending a PASV command string as the argument of another command to an FTP server, which generates a response that contains the string, causing IPFilter to treat the response as if it were a legitimate PASV command from the server.

Buffer overflow in lib/load_http.c in ippool in Darren Reed IPFilter (aka IP Filter) 4.1.31 allows local users to gain privileges via vectors involving a long hostname in a URL.

IPFilter 3.2.3 through 3.2.10 allows local users to modify arbitrary files via a symlink attack on the saved output file.

Race condition in IPFilter firewall 3.4.3 and earlier, when configured with overlapping "return-rst" and "keep state" rules, allows remote attackers to bypass access restrictions.
