Candidate: CVE-2011-2393
PublicDate: 2012-02-02
References:
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-2393
http://seclists.org/fulldisclosure/2011/Apr/86
http://www.mh-sec.de/downloads/mh-RA_flooding_CVE-2010-multiple.txt
Description:
The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in
FreeBSD, NetBSD, and possibly other BSD-based operating systems allows
remote attackers to cause a denial of service (CPU consumption and device
hang) by sending many Router Advertisement (RA) messages with different
source addresses, a similar vulnerability to CVE-2010-4670.
Ubuntu-Description:
Notes:
tyhicks> "Old Linux kernels are also affected, detailed version
information unknown."
apw> "Linux: fixed prior 2010"
apw> algorithm appears unchanged all the way back to hardy, with the
apw> holding of a single address from RA at any one time, very likely we
apw> are unaffected but this needs testing
jdstrand> linux-lts-saucy no longer receives official support
jdstrand> linux-lts-quantal no longer receives official support
apw> we have always had an upper limit of addresses for each interface via RA
apw> so we cannot crash at least, we only accept these from link-local so we
apw> can only be DOSd by someone on the local link, who can kill us by killing
apw> the same link. For this CVE we seemed to be fixed by the first git commit
apw> so use that as 'fix'.
