CVSS Base Score: 4.3 **CVSS Temporal Score:**See <https://exchange.xforce.ibmcloud.com/vulnerabilities/97013> for the current score *CVSS Environmental Score:**Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
IBM Personal Communications 6.0.11 and earlier.
Fix is available starting in Personal Communications 6.0.12
Clients who are on older unsupported versions of IBM Personal Communications are also advised to upgrade to IBM Personal Communications V6.0.12 or above.
IBM recommends that you review your entire environment to identify areas that enable the SSLv3 protocol and take appropriate mitigation and remediation actions. The most immediate mitigation action that can be taken is disabling SSLv3.
Please follow the instructions to ensure that IBM Personal Communications session is not configured to initiate use SSLv3 connection:

Click Link Parameters…
Click the Security Setup tab
If the Security Protocol drop-down list hasSSL only selected, change it to one of the following:
TLS1.0
TLS1.1
TLS1.2
Click Apply > OK
At the same time, ensure that the host (IBM System z, IBM System i, or any other VT hosts) have SSLv3 disabled.
**Important note:**IBM strongly suggests that all System z customers subscribe to the System z Security Portal to receive the latest critical System z security and integrity service. If you are not subscribed, see the instructions on the System z Security web site. Security and integrity APARs and associated fixes will be posted to this portal. IBM suggests reviewing the CVSS scores and applying all security or integrity fixes as soon as possible to minimize any potential risk.
