remote crash possibility of FW-1?

[Thomas Nau <thomas.nau () rz uni-ulm de>]

Hi there.
We use Checkpoints Firewall-I release 4.0 SP 4 running on a SUN U2/200
Solaris 2.6 with up-to-date patchlevel. For several weeks now the box
crashes or reboots without any hint left in the logfiles. SUN service
replaced all components (FDDI, RAM, CPUs, ...) except for the mirrored
disks. Since most of the crashes happen during the weekend we also suspect
some DOS attack. Are there any known DOS attacks than leave the box
unusable till someone does a power-off-on cycle?
