Summary: CVE-2012-4244: CSWbind unstable should be updated to
A nameserver can be caused to exit with a REQUIRE exception if it can be
induced to load a specially crafted resource record.
Document Version: 2.0
Posting date: 12 September 2012
Program Impacted: BIND
Versions affected: 9.0.x -> 9.6.x, 9.4-ESV->9.4-ESV-R5-P1,
9.6-ESV->9.6-ESV-R7-P2, 9.7.0->9.7.6-P2, 9.8.0->9.8.3-P2, 9.9.0->9.9.1-P2
If a record with RDATA in excess of 65535 bytes is loaded into a
nameserver, a subsequent query for that record will cause named to exit
with an assertion failure.
Please Note: Versions of BIND 9.4 and 9.5 are also affected, but these
branches are beyond their "end of life" (EOL) and no longer receive testing
or security fixes from ISC. For current information on which versions are
actively supported, please see http://www.isc.org/software/bind/versions.
This vulnerability can be exploited remotely against recursive servers by
inducing them to query for records provided by an authoritative server. It
affects authoritative servers if a zone containing this type of resource
record is loaded from file or provided via zone transfer.
