*******
The SSLv3 protocol and RC4 cipher suites should not be used due
to the POODLE and Bar Mitzvah vulnerabilities.
Problem Conclusion
An administrator can completely disable SSLv3 and RC4 cipher
suites for System SSL using the QSSLPCL and QSSLCSL system
values without this PTF.
This PTF removes SSLv3 from the eligible default protocol list
and the RC4 cipher suites from the eligible default cipher
specification list when they remain enabled by the system
values.
Applications coded to use the default values will no longer
negotiate the use of SSLv3 and RC4 with peers.
If SSLv3 or RC4 support is required by peers of such an
application after this PTF is applied, the values can be added
back to the System SSL eligible default lists using System
Service Tools (SST) Advanced Analysis Command SSLCONFIG.
To change the System SSL settings with the Start System Service
Tools (STRSST) command, follow these steps:
1. Open a character-based interface.
2. On the command line, type STRSST.
3. Type your service tools user name and password.
4. Select option 1 (Start a service tool).
5. Select option 4 (Display/Alter/Dump).
6. Select option 1 (Display/Alter storage).
7. Select option 2 (Licensed Internal Code (LIC) data).
8. Select option 14 (Advanced analysis).
9. Select option 1 (SSLCONFIG).
10. Enter -h
This will show the help screen that describes the input strings
to change the System SSL setting for -eligibleDefaultProtocols
and -eligibleDefaultCipherSuites.
