Security Bulletin: GNU C library (glibc) vulnerability affects IBM SDN-VE Unified Controller and IBM SDN-VE Service Appliance (CVE-2015-0235)

Summary

GNU C library (glibc) vulnerability that has been referred to as GHOST affects IBM SDN VE Unified Controller and IBM SDN VE Service Appliance.

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

Affected Products and Versions

IBM SDN VE, Unified Controller, KVM Edition: 1.2.2 and earlier
IBM SDN VE, Unified Controller, VMware Edition: 1.2.2 and earlier
IBM SDN VE, Unified Controller, OpenFlow Edition: 1.2.2 and earlier
IBM SDN VE, Service Appliance, KVM Edition: 1.2.2 and earlier

Remediation/Fixes

IBM recommends updating the affected IBM SDN VE, Unified Controllers and IBM SDN VE, Service Appliances to the latest versions for which IBM is providing a fix, which are identified below:
IBM SDN VE, Unified Controller, KVM Edition: 1.2.3
IBM SDN VE, Unified Controller, VMware Edition: 1.2.3
IBM SDN VE, Unified Controller, OpenFlow edition: 1.2.3
IBM SDN VE, Service Appliance, KVM Edition: 1.2.3
IBM SDN VE, Service Appliance, VMware Edition: 1.2.3
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.
