   An update that solves two vulnerabilities and has three
   fixes is now available.

Description:

   This update for openssl-1_0_0 to 1.0.2p fixes the following issues:

   These security issues were fixed:

   - Prevent One&Done side-channel attack on RSA that allowed physically
 near
     attackers to use EM emanations to recover information (bsc#1104789)
   - CVE-2018-0737: The RSA Key generation algorithm has been shown to be
     vulnerable to a cache timing side channel attack. An attacker with
     sufficient access to mount cache timing attacks during the RSA key
     generation process could have recovered the private key (bsc#1089039)
   - 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

   This non-security issue was fixed:

   - 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.
