RHEL 6 : glibc (RHSA-2016:1207)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An update for glibc is now available for Red Hat Enterprise Linux 6.5
Advanced Update Support.

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.

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) :

* It was discovered that, under certain circumstances, glibc's
getaddrinfo() function would send DNS queries to random file
descriptors. An attacker could potentially use this flaw to send DNS
queries to unintended recipients, resulting in information disclosure
or data loss due to the application encountering corrupted data.
(CVE-2013-7423)
