    <Note Title="Topic" Type="Summary" Ordinal="1" xml:lang="en">Security update for openssl-1_0_0</Note>
    <Note Title="Details" Type="General" Ordinal="2" xml:lang="en">This update for openssl-1_0_0 to 1.0.2p fixes the following issues:

These security issues were fixed:

- Prevent One&amp;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)
