Vulnerability Details
CVE ID: CVE-2014-0963
CVSS and DESCRIPTION: Please refer to the following link:
IBM Security Directory Server CPU utilization (CVE-2014-0963)
Affected Products and Versions
AIX 5.3, 6.1 and 7.1.
VIOS 2.2.x
Remediation/Fixes
The GSKit package contains a fix and needs to be installed on AIX/VIOS
systems.
If your GSKit is older than the corresponding levels that are in the following
list, update your GSKit to the specified version, or later. To determine
which version of the GSKit component is installed, enter the following
command:
lslpp -l | grep -i gsk
The fixes for the GSKit components can be downloaded at the following links:
GSKit V7.0.4.50
GSKit V8.0.14.43
GSKit V8.0.50.20
When you are using GSKitV8, your IBM Security Directory Server or IBM Tivoli
Directory Server must be at version 6.3.0.26 or higher. This version avoids a
compatibility issue between the IBM Security Directory Server component and
the new GSKitV8 fix packs. Refer to the above mentioned link under "CVSS and
DESCRIPTIONS". To determine the installed version of the IBM Security
Directory Server, enter the following command:
lslpp -l | grep idsldap
