+! CAN-2004-0460 - CERT VU#317350: Five stack overflow exploits were closed
+ in logging messages with excessively long hostnames provided by the
+ clients. It is highly probable that these could have been used by
+ attackers to gain arbitrary root access on systems using ISC DHCP 3.0.1
+ release candidates 12 or 13. Special thanks to Gregory Duchemin for
+ both finding and solving the problem.
+
+! CAN-2004-0461 - CERT VU#654390: Once the above was closed, an opening
+ in log_*() functions was evidented, on some specific platforms where
+ vsnprintf() was not believed to be available and calls were wrapped to
+ sprintf() instead. Again, credit goes to Gregory Duchemin for finding
+ the problem. Calls to snprintf() are now linked to a distribution-local
+ snprintf implementation, only in those cases where the architecture is
+ not known to provide one (see includes/cf/[arch].h). If you experience
+ linking problems with snprintf/vsnprintf or 'isc_print_' functions, this
+ is where to look. This vulnerability did not exist in any previously
+ published version of ISC DHCP.

+- Compilation on hpux 11.11 was repaired.

+ Changes since 3.0.1rc12
+
+- Fixed a bug in omapi lease lookup function, to form the hardware
+ address for the hash lookup correctly, thanks to a patch from
+ Richard Hirst.
+
+- Fixed a bug where dhcrelay was sending relayed responses back to the
+ broadcast address, but with the source's unicast mac address. Should
+ now conform to rfc2131 section 4.1.
+
+- Cross-compile bug fix; use $(AR) instead of ar. Thanks to Morten Brorup.
+
+- Fixed a crash bug in dhclient where dhcpd servers that do not provide
+ renewal times results in an FPE. As a side effect, dhclient can now
+ properly handle 0xFFFFFFFF (-1) expiry times supplied by servers. Thanks
+ to a patch from Burt Silverman.
+
+- The 'ping timeout' debugs from rc12 were removed to -DDEBUG only,
+ and reformatted to correct a compilation error on solaris platforms.
+
+- A patch was applied which fixes a case where leases read from the
+ leases database do not properly over-ride previously read leases.
+
+- dhcpctl.3 manpage was tweaked.
