Security issues fixed :

The 9 Lives of Bleichenbacher’s CAT: Cache Attacks on TLS Implementations (bsc#1117951)

CVE-2019-1559: Fixed OpenSSL 0-byte Record Padding Oracle which under certain circumstances a TLS server can be forced to respond differently to a client and lead to the decryption of the data (bsc#1127080).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
