Oracle Linux 6 : glibc (ELSA-2014-1391)

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.

Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2014:1391 :

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

Red Hat Product Security has rated this update as having Moderate
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.

The glibc packages provide the standard C libraries (libc), POSIX
thread libraries (libpthread), standard math libraries (libm), and the
Name Server Caching Daemon (nscd) used by multiple programs on the
system. Without these libraries, the Linux system cannot function

An out-of-bounds write flaw was found in the way the glibc's
readdir_r() function handled file system entries longer than the
NAME_MAX character constant. A remote attacker could provide a
specially crafted NTFS or CIFS file system that, when processed by an
application using readdir_r(), would cause that application to crash
or, potentially, allow the attacker to execute arbitrary code with the
privileges of the user running the application. (CVE-2013-4237)

It was found that getaddrinfo() did not limit the amount of stack
memory used during name resolution. An attacker able to make an
application resolve an attacker-controlled hostname or IP address
could possibly cause the application to exhaust all stack memory and
crash. (CVE-2013-4458)

These updated glibc packages also include several bug fixes and two
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 6.6
Technical Notes, linked to in the References section, for information
on the most significant of these changes.

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