  script_tag(name:"insight", value:"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)

  This update was imported from the SUSE:SLE-15:Update update project.

  Patch Instructions:

  To install this openSUSE Security Update use the SUSE recommended
  installation methods
  like YaST online_update or 'zypper patch'.

  Alternatively you can run the command listed for your product:

  - openSUSE Leap 15.0:

  zypper in -t patch openSUSE-2018-1109=1");

  script_tag(name:"affected", value:"openssl-1_1 on openSUSE Leap 15.0.");

  script_tag(name:"solution", value:"Please install the updated package(s).");

  script_tag(name:"solution_type", value:"VendorFix");
  script_tag(name:"qod_type", value:"package");
