RHBA-2012:0763 - Bug Fix Advisory

Topic

Updated glibc packages that fix multiple bugs and add one enhancement are now
available for Red Hat Enterprise Linux 6.

Description

The glibc packages provide the standard C and standard math libraries used by
multiple programs on the system. Without these libraries, the Linux system
cannot function correctly.

These updated glibc packages include numerous bug fixes and one enhancement.
Space precludes documenting all of these changes in this advisory. Users are
directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on
the most significant of these changes:

Users of glibc are advised to upgrade to these updated packages, which fix these
bugs and add this enhancement.
