Upstream has issued an advisory on December 8:
The issue (CVE-2014-8500) is fixed upstream in 9.9.6-P1 (for Mageia 4):
This is essentially the same issue as CVE-2014-8601 for PowerDNS Recursor (Bug 14695).
Only affecting Cauldron is another issue announced on December 8:
That issue (CVE-2014-8680) is fixed in 9.10.1-P1:
Updated packages uploaded for Mageia 4 and Cauldron.
Updated bind packages fix security vulnerability:
By making use of maliciously-constructed zones or a rogue server, an attacker
can exploit an oversight in the code BIND 9 uses to follow delegations in the
Domain Name Service, causing BIND to issue unlimited queries in an attempt to
follow the delegation. This can lead to resource exhaustion and denial of
service (up to and including termination of the named server process)
Updated packages in core/updates_testing:
