Release Notes

• Because the xterm binary had the set group ID (setgid) bit configured, certain environmental

variables (such as LD_LIBRARY_PATH and TMPDIR) were unset. In this release, the xterm binary

now has mode 0755 permissions configured, which resolves this issue.

• The recommended method for balancing the load on NIS servers when multiple machines are

connecting with ypbind has changed with this release. The ypbind daemon's behavior has not

changed: it still pings all NIS servers listed in the /etc/ypbind configuration file and then binds to

the single fastest-responding server. Before, it was recommended to list all available NIS servers

in each machine's /etc/ypbind.conf configuration file. However, because even servers under

high load can respond quickly to this ping, thus inadvertently increasing their own load, it is now

recommended for administrators to list a smaller number of available NIS servers in each machine's

ypbind.conf, and to vary this list across machines. In this way, NIS servers are automatically load-

balanced due to not every NIS server being listed as being available to every machine.

• OpenMotif has been re-based to upstream version 2.3.1. This update applies several bug fixes,

including:

• A bug in the way OpenMotif handled the Grab and Ungrab events is now fixed. In previous

releases, this bug could cause the display to lock.

• A bug in nedit could cause it to crash when using the nedit graphical user interface. This

was caused by a function in the code that causes a segmentation fault in some cases of item

selection, which is now fixed.

• dbus has been re-based to version 1.1.2. This update fixes a bug wherein multi-threaded programs

could cause a deadlock in dbus. In previous releases, as one thread listened to dbus and

processed messages, the second thread would send messages to dbus.

• strace has been re-based to version 4.5.18. This fixes several bugs, including:

• A bug that caused strace to crash when the -f option was used on some multi-threaded

programs (particularly on 64-bit systems) is now fixed.

• A bug that prevented the 64-bit version of strace from executing a vfork() function call on a 32-

bit process is now fixed.

• cpuspeed has been updated to version 1.2.1-5. With this update, the cpuspeed init script now

loads the speedstep-centrino module if all other module loads fail. In addition, a user-space

bug that prevented the Powernow-k8 module from loading is now fixed.

• The frysk suite of tools have been removed completely from this distribution. frysk was originally

introduced as a technology preview in Red Hat Enterprise Linux 5.0.

• Previously, the partition I/O statistics provided by the iostat -x command were incomplete. In

this update, partition statistics are now calculated in the same manner as disk statistics, providing

coherent and comprehensive I/O statistics at the partition level.

• A password disclosure flaw was found with configuration file for the Dovecot mail server. If a

system had the ssl_key_password option defined, any local user could view the SSL key

password. (CVE-2008-4870)
