Re: [Full-disclosure] [CVE-2012-0207] Linux IGMP Remote Denial Of Service



Try fixing the in_cksum() function, it has been intionally
crippled,also,look at both of the 'ips' both should really be argvs,as
theyre set in saddr/daddr;)
this should be easy to fix, or read the pasted one i think is in one
of my posts in reply to it, it will show where i had to adjust it, as
the sendto, will never work with the in_cksum not functional, lan, or
no lan...
anyhow, you could ignore me, but in the end, read the code... later dude.

Thanks again for re-enforcing my paranoia with another one of your exploits.
The apache killer one was particularly disturbing and at the same time,
another great eye-opener, much respect to you.

I tested this on a custom compiled kernel for PXE booting, version
2.6.37.6-x86_64, running Debian Squeeze, and I can't seem to get it to work.
Root is mounted read-only over NFS.

I don't recall any special config options I did for networking or IGMP
requests, other then building my NIC drivers and NFS into the kernel.
Did I just get lucky?

Thanks,

Morgus
