  <description>This update for openssl-1_1 to 1.1.0i fixes the following issues:

These security issues were fixed:

- CVE-2018-0732: During key agreement in a TLS handshake using a DH(E) based
  ciphersuite a malicious server could have sent a very large prime value to the
  client. This caused the client to spend an unreasonably long period of time
  generating a key for this prime resulting in a hang until the client has
  finished. This could be exploited in a Denial Of Service attack (bsc#1097158)
- Make problematic ECDSA sign addition length-invariant
- Add blinding to ECDSA and DSA signatures to protect against side channel attacks

These non-security issues were fixed:

- When unlocking a pass phrase protected PEM file or PKCS#8 container, we now
  allow empty (zero character) pass phrases.
- Certificate time validation (X509_cmp_time) enforces stricter compliance with
  RFC 5280. Fractional seconds and timezone offsets are no longer allowed.
- Fixed a text canonicalisation bug in CMS
- Add openssl(cli) Provide so the packages that require the openssl binary can
  require this instead of the new openssl meta package (bsc#1101470)
