Impact
An attacker may be able to derive the TLS session key and fully
decrypt the TLS traffic to access any sensitive information that is
transmitted, such as login credentials and credit card numbers.
Recommendations
System administrators will need to patch their systems if their TLS
are implemented using RSA ciphers by the affected vendors/implementations.
Visit https://robotattack.org for more information on the
respective vendor's patches.
If patches are not available, consider disabling TLS RSA cipher
suites,
possible, with the help of the product's documentation or seekassistance
from the vendor.for
Disabling RSA ciphers on a V7R1 system will basically break SSL,
since
V7R1 only supports RSA ciphers.
Would need to upgrade to V7R2 or V7R3 for the newer ciphers.
For those running SSL on V7R1, is this the end?

Hi Rob:
We updated the cipher specs (via the notes.ini) and now pass the
test
Bleichenbacher's Oracle Threat (ROBOT) for both traveler and dominomidrange-l@xxxxxxxxxxxx<
SSLCipherSpec=C030009FC02F009EC028006BC0270067
This fixes domino but now we have to handle the IBMi apache servers
as well.
