=====================================================================

1. Summary:

An update for glibc is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

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

3. Description:

The glibc packages provide the standard C libraries (libc), POSIX thread
libraries (libpthread), standard math libraries (libm), and the name
service cache daemon (nscd) used by multiple programs on the system.
Without these libraries, the Linux system cannot function correctly.

Security Fix(es):

* glibc: Buffer overflow in glob with GLOB_TILDE (CVE-2017-15670)

* glibc: Buffer overflow during unescaping of user names with the ~
operator (CVE-2017-15804)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 6.10 Release Notes and Red Hat Enterprise Linux 6.10
Technical Notes linked from the References section.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

For the update to take effect, all services linked to the glibc library
must be restarted, or the system rebooted.

5. Bugs fixed (https://bugzilla.redhat.com/):

1437147 - Fix for thread cancellation of IdM functions incorrect in rhel-6.9.
1504804 - CVE-2017-15670 glibc: Buffer overflow in glob with GLOB_TILDE
1505298 - CVE-2017-15804 glibc: Buffer overflow during unescaping of user names with the ~ operator
