====================================================================
1. Summary:

Updated coreutils packages that fix three security issues, several bugs,
and add two enhancements are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having low
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

3. Description:

The coreutils package contains the core GNU utilities. It is a combination
of the old GNU fileutils, sh-utils, and textutils packages.

It was discovered that the sort, uniq, and join utilities did not properly
restrict the use of the alloca() function. An attacker could use this flaw
to crash those utilities by providing long input strings. (CVE-2013-0221,
CVE-2013-0222, CVE-2013-0223)

These updated coreutils packages include numerous bug fixes and two
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical
Notes, linked to in the References, for information on the most significant
of these changes.

All coreutils users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues and add these
enhancements.

4. Solution:

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