Subject: [dns-operations] Update: BIND 9 recursive error being investigated
To: dns-operations AT mail.dns-oarc.net



Interm Security Advisory:
http://www.isc.org/software/bind/advisories/cve-2011-tbd (CVE will be
updated)

Organizations across the Internet are reporting crashes interrupting
service on BIND 9 nameservers performing recursive queries. Affected
servers crash after logging an error in query.c with the following
message: "INSIST(! dns_rdataset_isassociated(sigrdataset))"

Multiple versions are reported as being affected, including all
currently supported release versions of ISC BIND 9.

ISC is actively investigating the root cause and working to produce
patches which avoid the crash. Further information will be made
available soon (see the advisory
http://www.isc.org/software/bind/advisories/cve-2011-tbd).

It is unknown at this time if this is an exploited attack. This is
under investigation.

Questions, observations, and data is welcomed. Please send to
security-officer AT isc.org.
