Hey guys,

Wondering if anyone is aware of a 0day BIND vuln/expl floating around in the wild. A few networks have got`n hit and Id like to make sure mine is ready if an attack does find its way to my door steps.

Some logs from a friends network that did get hit with it:

Nov 15 20:50:17 nc-ns-2 named[2859]: query.c:1781: INSIST(! dns_rdataset_isassociated(sigrdataset)) failed
Nov 15 20:50:17 nc-ns-2 named[2859]: exiting (due to assertion failure)

[5111275.374242] UDP: short packet: From 194.116.73.150:0 52376/1480 to dst-IP-x.x.x.x:0 [5111788.558808] UDP: short packet: From 216.86.101.76:0 52376/1480 to dst-IP-x.x.x.x:0 [5111910.128768] UDP: short packet: From 194.116.73.150:0 52376/1480 to dst-IP-x.x.x.x:0 [5112394.335742] UDP: short packet: From 216.86.101.76:0 52376/1480 to dst-IP-x.x.x.x:0 [5115826.265834] UDP: short packet: From 50.0.0.0:0 52376/1480 to dst-IP-x.x.x.x:0

(dst-IP-x.x.x.) used to hid his real dns ip of course

nc-nscache-2:~# dpkg -l | grep bind
ii bind9 1:9.6.ESV.R4+dfsg-0+lenny3 Internet Domain Name Server

we found a few links to cvs with a vuln like this one but they have since all been fixed/updated.

With all do respect please don't reply with "solution = don't run bind"

Cheers
