1.16.2. RHBA-2009:1137: bug fix update
Note
This update has already been released (prior to the GA of this release) as errata
RHBA-2009:1137

Updated bind packages that resolve an issue are now available for Red Hat Enterprise Linux 5.
The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS)
protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use
when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.
These updated bind packages fix the following bug:
• DNSSEC, the Domain Name System Security Extensions, are a set of specifications used to secure
information provided by the domain name system. One of the specifications, DNSSEC Lookaside
Validation (DLV), failed to handle unknown algorithms, which caused the name resolution of "gov"
and "org" top-level domains to fail. DLV in these updated packages is now able to handle unknown
algorithms, and thus the validation and resolution of top-level domains (such as "org" and "gov")
succeeds, thus resolving the issue. (
BZ#504794

All users of bind are advised to upgrade to these updated packages, which resolve this issue.
1.16.3. RHBA-2009:1420: bug fix and enhancement update
Updated bind packages that fix several bugs and add various enhancements are now available for
Red Hat Enterprise Linux 5.
The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS)
protocols. BIND includes a DNS server (named), a resolver library (routines for applications to use
when interfacing with DNS), and tools for verifying that the DNS server is operating correctly.
This update upgrades the bind packages to upstream version 9.3.6-P1, which contains bug fixes and
enhancements over the previous version.
Notably, this updated BIND is able to handle a much larger number of requests simultaneously.

BZ#457036

)
These updated bind packages provide fixes for the following bugs:
• named occasionally crashed due to an assertion failure, and logged this error message to the
system log:
named[PID]: socket.c:1649: INSIST(!sock->pending_recv) failed
named[PID]: exiting
This crash was caused by sockets being closed too early. With these updated packages, this
assertion failure no longer occurs. (
BZ#455802

)
• when using the '-4' option with the "host" and "dig" utilities to force them to use an IPv4 transport,
the order in which IPv4 and IPv6 nameservers were listed in the /etc/resolv.conf configuration file
