Default glibc security update (RHSA-2015-0099)

Avaya have feedback the following:

glibc security update (RHSA-2015-0099)

Original Release Date: January 28, 2015
Last Revised: January 28, 2015
Number: ASA-2015-047
Risk Level: None
Advisory Version: 1.0
Advisory Status: Final

1. Overview:

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.
A heap-based buffer overflow was found in glibc's __nss_hostname_digits_dots() function, which is used by the gethostbyname() and gethostbyname2() glibc function calls. A remote attacker able to make an application call either of these functions could use this flaw to execute arbitrary code with the permissions of the user running the application. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0235 to this issue.
No Avaya system products are vulnerable, as the affected RHEL AUS, EUS and LL Operating Systems are not installed by default.
More information about these vulnerabilities can be found in the security advisory issued by Red Hat:
2. Avaya System Products using a RHEL AUS, EUS or LL Operating System: None

3. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that come with the operating system. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.
In the case of this advisory Avaya software-only products are not affected by the vulnerability directly but the underlying Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
Product: Actions: Avaya Aura® Application Enablement Services Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the AES application. Avaya IQ Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the Avaya IQ application. CVLAN Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the CVLAN application. Avaya Aura® Experience Portal Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the EP application. Avaya Integrated Management Suite (IMS) Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the IMS application. Avaya Aura® Presence Services Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the PS application.
Recommended Actions for Software-Only Products:
In the event that the affected package is installed, Avaya recommends following recommended actions supplied by Red Hat regarding their Enterprise Linux.
