Summary
The IBM Tivoli Storage Manager (TSM) server and storage agent are affected
by a problem related to the SSL implementation which, under very specific
conditions, can cause CPU utilization to rapidly increase.
Vulnerability Details
CVE ID: CVE-2014-0963
DESCRIPTION:
TSM server and storage agent are affected by a problem with the handling
of certain SSL messages. The TLS implementation can, under very specific
conditions, cause CPU utilization to rapidly increase. The situation occurs
only in a certain error case that causes a single thread to begin looping. If
this happens multiple times, more threads will begin to loop and an increase
in CPU utilization will be seen. This increase could ultimately result in
CPU exhaustion and unresponsiveness of the Tivoli Storage Manager server
and/or storage agent and other software running on the affected system.
This issue can affect the availability of the system, but does not impact
system confidentiality or integrity. This vulnerability can be remotely
exploited, authentication is not required and the exploit is moderately
complex.
To determine if your systems are being affected by this issue, you can
monitor the CPU utilization for Tivoli Storage Manager instances.

IBM Tivoli Storage Manager Server 6.1 Please note that IBM has previously announced End of Support for these
and 5.5, on AIX and Windows only versions, effective April 30, 2014.
IBM recommends using the Workaround specified below, or upgrading to a
fixed, supported release
Workarounds and Mitigations
Method One) Monitor CPU utilization of your Tivoli Storage Manager server
and/or storage agent instances. If utilization becomes abnormally high,
stop and restart the affected instance.
Method Two) Disable the use of TLS in Tivoli Storage Manager. To do this,
perform the following for every Server or Storage agent instance in your
environment:
1. For every server, update the options file
( server - dsmserv.opt or storage agent - dsmsta.opt ), by commenting out
the options
statement "SSLTCPPORT xxxx" and "SSLTCPADMINPORT xxxx".
Commenting out entails placing an asterisk at the beginning of the line
containing "SLTCPPORT" and/or "SSLTCPADMINPORT".
2. Ensure that a TCPPORT or TCPADMINPORT options statement is in the
options file and
not commented out.
3. Update all server and storage agent definitions to use the TCP port
rather than the SSL port
in each server and storage agent. For storage agents, you can re-define
the setup by using
the dsmsta setstorageserver command and not using the SSL=YES parameter.
4. Update all client options files by commenting out the "SSL YES" option
in their respective
dsm.sys files and/or options files. Note: A new level of the client is
notrequired for this issue.
5. Stop and re-start all storage agents and servers. Then, stop and start
all clients and client
schedulers that are using SSL as their communication methods.
