DB2 FOR LUW / DB2FORLUW / A10 - DB2

The TLS padding vulnerability could allow a remote attacker to 
obtain sensitive information, caused by the failure to check the 
contents of the padding bytes when using CBC cipher suites of 
some TLS implementations. A remote user with the ability to 
conduct a man-in-the-middle attack could exploit this 
vulnerability via a POODLE (Padding Oracle On Downgraded Legacy 
Encryption) like attack to decrypt sensitive information and 
calculate the plaintext of secure connections. 
 
Customers have Secure Sockets Layer (SSL) support enabled in 
their DB2 database system are affected. SSL support is not 
enabled in DB2 by default.
