Synopsis:          Moderate: glibc security, bug fix, and enhancement update
Advisory ID:       RHSA-2018:3092-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2018:3092
Issue date:        2018-10-30

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

1. Summary:

An update for glibc is now available for Red Hat Enterprise Linux 7.

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.

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: Incorrect handling of RPATH in elf/dl-load.c can be used to
execute code loaded from arbitrary libraries (CVE-2017-16997)

* glibc: Integer overflow in posix_memalign in memalign functions
(CVE-2018-6485)

* glibc: Integer overflow in stdlib/canonicalize.c on 32-bit architectures
leading to stack-based buffer overflow (CVE-2018-11236)

* glibc: Buffer overflow in __mempcpy_avx512_no_vzeroupper (CVE-2018-11237)

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 7.6 Release 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.
