Red Hat Security Advisory

 

Synopsis: Moderate: glibc security update

Advisory ID: RHSA-2016:1207-01

Product: Red Hat Enterprise Linux

Advisory URL: https://access.redhat.com/errata/RHSA-2016:1207

Issue date: 2016-06-07

CVE Names: CVE-2013-7423

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

 

1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Server AUS (v. 6.5) - x86_64

Red Hat Enterprise Linux Server Optional AUS (v. 6.5) - 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):

 

* 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)

 

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/):

 

1187109 - CVE-2013-7423 glibc: getaddrinfo() writes DNS queries to random file descriptors under high load
