APAR Error Description / Circumvention

-----------------------------------------------
The RSA_MD5 protocol should not be used for TLSv1.2 signature
and hash operations due to the SLOTH vulnerabilities.

CORRECTION FOR APAR SE63797 :
-----------------------------
An administrator can completely disable the RSA_MD5 signature
and hash algorithm from being used by System SSL/TLS using the
System Service Tools (SST) Advanced Analysis Command SSLCONFIG
values without this PTF.  This is done by manually removing
RSA_MD5 from the default signature algorithm list.

CIRCUMVENTION FOR APAR SE63797 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


None.


Default Instructions

THIS PTF CAN BE APPLIED IMMEDIATE OR DELAYED.
