I've had a report from someone with clue (and tcpdump) that a properly
functioning DNS resolver that correctly uses randomised source ports
magically becomes vulnerable once the traffic's passed through a
Checkpoint firewall, where Dan Kaminsky's tool shows:
(note the incrementing port numbers.)
Can anyone else confirm this behaviour?
Checkpoint are one of the dozens of vendors listed on the CERT
advisory as "Status: Unknown"
They do have an advisory up:
I don't have the login needed to read the whole thing, but the front
page just says:
"Protection provided by:
VPN-1: * NGX R65
* NGX R62
* NGX R61
* NGX R60
[...etc, etc...] "
