Summary
Security update for openssl-1_1
Details

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 (X509cmptime) 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)
