Description

This update for openssl 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)

These non-security issues were 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)

  • Fixed path to the engines which are under /lib64 on SLE-12 (bsc#1101246, bsc#997043)

This update was imported from the SUSE:SLE-12-SP2:Update update project.
