Description

This update for openssl fixes the following issues :

CVE-2018-0732: Reject excessively large primes in DH key generation (bsc#1097158)

CVE-2018-0734: Timing vulnerability in DSA signature generation (bsc#1113652)

CVE-2018-0737: Cache timing vulnerability in RSA Key Generation (bsc#1089039)

CVE-2018-5407: Elliptic curve scalar multiplication timing attack defenses (fixes 'PortSmash') (bsc#1113534)

CVE-2019-1559: Fix 0-byte record padding oracle via SSL_shutdown (bsc#1127080)

Fix One&Done side-channel attack on RSA (bsc#1104789)

Reject invalid EC point coordinates (bsc#1131291)

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

Add missing error string to CVE-2016-8610 fix (bsc#1110018#c9)

blinding enhancements for ECDSA and DSA (bsc#1097624, bsc#1098592)

Non security fixes: correct the error detection in the fips patch (bsc#1106197)

Add openssl(cli) Provide so the packages that require the openssl binary can require this instead of the new openssl meta package (bsc#1101470)

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.
