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

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:
