potential DoS of tcplogd in package iplogger

[Ralf Nyren <plumbum@linux.nu>]

Hi!

I don't if this is already known but I thought it might be worth a notice.

In package iplogger there is a daemon, tcplogd, which logs incoming
tcp-connection attempts to syslog.
 It seems that this daemon forks a child for every connection discovered and
if for example the machine running tcplogd is syn-flooded there will be a
lot of tcplogd's forked.
 The tcplogd processes will die of by time but during the attack the machine
will be more or less inaccessable.


Info: 
iplogger 1.1-4
no syn-cookies support in kernel (2.2.12)
