Security Bulletin

Summary

GNU C library (glibc) vulnerability that has been referred to as GHOST 
affects IBM PureData System for Operational Analytics.
Vulnerability Details

CVEID: CVE-2015-0235

DESCRIPTION:

The gethostbyname functions of the GNU C Library (glibc) are 
vulnerable to a buffer overflow. By sending a specially crafted, but valid 
hostname argument, a remote attacker could overflow a buffer and execute 
arbitrary code on the system with the privileges of the targeted process or 
cause the process to crash. The impact of an attack depends on the 
implementation details of the targeted application or operating system. This 
issue is being referred to as the "Ghost" vulnerability.

CVSS Base Score: 7.6

CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/100386 

CVSS Environmental Score*: Undefined

CVSS Vector: (AV:N/AC:H/Au:N/C:C/I:C/A:C)

Once updates have been applied, any process using glibc will need to be 
restarted. Given that nearly all system processes use glibc, rebooting after 
upgrading is suggested.

IBM recommends that you review your entire environment to identify vulnerable 
releases of glibc including your Operating Systems and take appropriate 
mitigation and remediation actions. Please contact your Operating System 
provider for more information.

For assistance, contact IBM Support:

* In the United States and Canada dial 1-800-IBM-SERV
* View the support contacts for other countries outside of the United States.
* Electronically open a Service Request with IBM Support.
