| Description |
A nameserver can be caused to exit with a REQUIRE exception if it can be induced to load a specially crafted resource record. CVE: CVE-2012-4244 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 Severity: Critical Exploitable: Remotely Description: 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. [^] Impact: 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. CVSS Score: 7.8 CVSS Equation: (AV:N/AC:L/Au:N/C:N/I:N/A:C) For more information on the Common Vulnerability Scoring System and to obtain your specific environmental score please visit: http://nvd.nist.gov/cvss.cfm?calculator&adv&version=2&vector=(AV:N/AC:L/Au:N/C:N/I:N/A:C) [^] Workarounds: Workarounds are under investigation, but none are known at this time. Active exploits: No known active exploits. Solution: Upgrade to the patched version or new release most closely related to your current version of BIND. The patched versions of BIND can be downloaded from http://www.isc.org/downloads/all. [^] The new release versions will be available within the next week.
