glibc bugfix errata

New glibc packages that fix a number of bugs are now available.

The glibc packages contain standard libraries that are used by many programs.

The following bugs have been fixed:

- A bug in pthread_cond_wait() which could cause programs hangs in some cases

- A bug in pthread_cond_timedwait() which could lead to crashes during
pthread_exit or thread cancellation

- Problems with destructors registered with pthread_key_create()

- glibc 2.0.x compatibility was missing

Users impacted by these bugs should upgrade to the updated glibc packages,
which resolve these problems.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

Once the glibc upgrade has been completed, you must either reboot the
system, or restart all daemons and other programs to avoid having two
copies of the libraries mapped into memory and mixing old libraries with
new ones during dlopening.
