[installer 2101] ISC dhcp-3.1.3

ISC dhcp-3.1.3 出ています。

☆ ISC dhcp-3.1.3
http://www.isc.org/sw/dhcp
ftp://ftp.isc.org/isc/dhcp/dhcp-3.1.3.tar.gz

Changes since 3.1.3rc1

- None.

Changes since 3.1.3b1

- None.

Changes since 3.1.2

- Remove infinite loop in token_print_indent_concat().

- Validate the argument to the -p option.

- The notorious 'option <unknown> ... larger than buffer' log line,
which is seen in some malformed DHCP client packets, was modified.
It now logs the universe name, and does not log the length values
(which are bogus corruption read from the packet anyway). It also
carries a hopefully more useful explanation.

- The db-time-format option was documented in manpages.

- Using reserved leases no longer results in 'lease with binding state
free not on its queue' error messages, thanks to a patch from Frode
Nordahl.

- A parser bug was fixed that segfaulted if site-option-space was tried
to be used interchangeably with vendor-option-space.

- Two uninitialized stack structures are now memset to zero, thanks to
patch from David Cantrell at Red Hat.

- The update-conflict-detection feature would leave an FQDN updated without
a DHCID (still currently implemented as a TXT RR). This would cause later
expiration or release events to fail to remove the domain name. The feature
now also inserts the client's up to date DHCID record, so records may safely
be removed at expiration or release time. Thanks to a patch submitted by
Christof Chen.

- Memory leak in the load_balance_mine() function is fixed. This would
leak ~20-30 octets per DHCPDISCOVER packet while failover was in use
and in normal state.

- Various compilation fixes have been included for the memory related
DEBUG #defines in includes/site.h.

- Fixed setting hostname in Linux hosts that require hostname argument
to be double-quoted. Also allow server-provided hostname to
override hostnames 'localhost' and '(none)'.

- Added client support for setting interface MTU and metric, thanks to
Roy "UberLord" Marples <roy@xxxxx>.

- Fixed failover reconnection retry code to continue to retry to reconnect
rather than restarting the listener.

- Fixed a bug where an OMAPI socket disconnection message would not result
in scheduling a failover reconnection, if the link had not negotiated a
failover connect yet (e.g.: connection refused, asynch socket connect()
timeouts).

- A bug was fixed that caused the 'conflict-done' state to fail to be parsed
in failover state records.

! A stack overflow vulnerability was fixed in dhclient that could allow
remote attackers to execute arbitrary commands as root on the system,
or simply terminate the client, by providing an over-long subnet-mask
option. CERT VU#410676 - CVE-2009-0692

- Versions 3.0.x syntax with multiple name->code option definitions is now
supported. Note that, similarly to 3.0.x, for by-code lookups only the
last option definition is used.

- Fixed a bug where a time difference of greater than 60 seconds between a
failover pair could cause the primary to crash on contact with the
secondary. Thanks to a patch from Steinar Haug.

- Secondary servers in a failover pair will now perform ddns removals if
they had performed ddns updates on a lease that is expiring, or was
released through the primary. As part of the same fix, stale binding scopes
will now be removed if a change in identity of a lease's active client is
detected, rather than simply if a lease is noticed to have expired (which it
may have expired without a failover server noticing in some situations).

- A patch supplied by David Cantrell at RedHat was applied that detects
invalid calling parameters given to the ns_name_ntop() function.
Specifically, it detects if the caller passed a pointer and size pair
that causes the pointer to integer-wrap past zero.

! Fixed a fenceposting bug when a client had two host records configured,
one using 'uid' and the other using 'hardware ethernet'. CVE-2009-1892
