Scientific Linux Security Update : glibc on SL6.x i386/x86_64

This script is Copyright (C) 2012-2016 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

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 properly.

Multiple errors in glibc's formatted printing functionality could
allow an attacker to bypass FORTIFY_SOURCE protections and execute
arbitrary code using a format string flaw in an application, even
though these protections are expected to limit the impact of such
flaws to an application abort. (CVE-2012-3404, CVE-2012-3405,

This update also fixes the following bug :

- A programming error caused an internal array of
nameservers to be only partially initialized when the
/etc/resolv.conf file contained IPv6 nameservers.
Depending on the contents of a nearby structure, this
could cause certain applications to terminate
unexpectedly with a segmentation fault. The programming
error has been fixed, which restores proper behavior
with IPv6 nameservers listed in the /etc/resolv.conf

All users of glibc are advised to upgrade to these updated packages,
which contain backported patches to fix these issues.
