Protecting old Linux hosts against TCP Sack Panic with SRX, hoe?

$

I have a Linux Servers network that sits beihnd a SRX device.

Some of them cannot be upgraded and are vulnerable to TCP Sack Panic CVE.
I cannot upgrade these Servers at the time and on more then one node there is no iptables compiled in the kernel.

The Ubuntu, RedHat and others give couple recommendations.(https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SACKPanic)

The most sano of them for my systems is the one which ipables drops every packet with mss between 0 to 500.

iptables -I FORWARD 1 -p tcp -m tcpmss --mss 1:500 -j DROP

I was wondering if is there any possible way to do the same on SRX to proctect my vulnurable hosts?

 

Thanks,

Eliezer
