Oracle Linux 5 : glibc (ELSA-2015-1627)

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

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

Description :

From Red Hat Security Advisory 2015:1627 :

Updated glibc packages that fix one security issue are now available
for Red Hat Linux 5.

Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link 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
correctly.

An invalid free flaw was found in glibc's getaddrinfo() function when
used with the AI_IDN flag. A remote attacker able to make an
application call this function could use this flaw to execute
arbitrary code with the permissions of the user running the
application. Note that this flaw only affected applications using
glibc compiled with libidn support. (CVE-2013-7424)

All glibc users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue.
