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.
