DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problem description: | |
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. | |
