Vulnerability Details
CVEID: CVE-2015-7442
DESCRIPTION: There is a "/tmp" race condition in IBM's Installation Manager "consoleinst.sh" script that could allow a local user to obtain administrator access. If a local user can guess the PID of the installation script when executed by an administrator then they could place a malicious script in its place to be executed as root. Note that the Installation Manager "consoleinst.sh" script is only useful during a console mode install from a multi-CD/DVD disk set and it is not documented.

Workarounds and Mitigations
The "consoleinst.sh" script has a vulnerability and should not be used. Users who need to perform an install from multi-disk product media using the Installation Manager's console mode, can install the Installation Manager first and then perform the product multi-disk install as a second step:
- Use the installc, userinstc, and groupinstc launchers with "-c" option, on the Install Packages page, uncheck everything but the IM offering and just install and/or update the Installation Manager offering.
- After the step 1 install of the Installation Manager completes, launch the installed IM in console mode specifying the "install.xml" response file on the CD/DVD .
e.g. "/opt/IBM/InstallationManager/eclipse/tools/imcl -c -input <IM installkit location on CD/DVD>/install.xml"
