[FW-1] firewall logs DoS



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
 
Hello,
 
I have a FW-1 NG FP1 firewall running on solaris 7. Space for /opt
was hogged today after doing a fw logswitch from the command
terminal. As a consequence policies could not be saved, and after
bouncing the firewall it did not come back up.
 
After identifying the problem and removing the switched logs the log
viewer did not register any accepted packets. These had track log,
and all I was viewing were rejected and dropped packets. Another
consequence was that all connections had th_flags, message: TCP
address spoofing   warning in the info field.  I one'd
fw_allow_tcp_out_of_state and then cero' ed it back and did no longer
perceive such behavior.
 
My Q is, does the firewall become unstable when this kind of thing
happens? Is the log viewer part normal?
 
thanks,
 
oscar
