Updated glibc packages are available

Updated glibc packages are available to fix an overflowable buffer
and for 7.x to fix a couple of non-security related bugs.

An overflowable buffer exists in earlier versions of glibc glob(3)
implementation. It may be possible to
exploit programs that pass user modifiable input to the glibc glob
function.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2001-0886 to this issue.

This errata also fixes a couple of non-security related bugs
in glibc packages for Red Hat Linux 7.x.
There was a bug in the dynamic linker which caused DT_RUNPATH dynamic
tags (e.g. created by GNU ld with --enable-new-dtags -rpath DIR options)
to behave the same way as mere DT_RPATH tag, ie. search paths in it
couldn't be overridden by LD_LIBRARY_PATH environment variable;
this is fixed in the updated packages, as well as a strndup bug
when strndup was used with string literal argument and a typo in
<inttypes.h> header.

It is recommended that all users upgrade to provided packages.

We'd like to thank Flavio Veloso <flaviovs@magnux.com> for discovering
this buffer overflow problem.

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.
