[ 21:19:20 dougb ] bind98dns BIND DNS suite with updated DNSSEC and DNS64
Update to versions 9.8.0-P4, 9.7.3-P3, and 9.6-ESV-R4-P3.
ALL BIND USERS ENCOURAGED TO UPGRADE IMMEDIATELY
This update addresses the following vulnerabilities:
A defect in the affected BIND 9 versions allows an attacker to remotely
cause the "named" process to exit using a specially crafted packet. This
defect affects both recursive and authoritative servers. The code location
of the defect makes it impossible to protect BIND using ACLs configured
within named.conf or by disabling any features at compile-time or run-time.
A defect in the affected versions of BIND could cause the "named" process
to exit when queried, if the server has recursion enabled and was
configured with an RPZ zone containing certain types of records.
Specifically, these are any DNAME record and certain kinds of CNAME
Additional changes in this version:
* If named is configured to be both authoritative and resursive and
receives a recursive query for a CNAME in a zone that it is
authoritative for, if that CNAME also points to a zone the server
is authoritative for, the recursive part of name will not follow
the CNAME change and the response will not be a complete CNAME
chain. [RT #24455]
Thus the patch for this bug has been removed from the port
* Using Response Policy Zone (RPZ) to query a wildcard CNAME label
with QUERY type SIG/RRSIG, it can cause named to crash. Fix is
query type independant. [RT #24715] [CVE-2011-1907]
