Calendar Grey September 30, 2018
Dist Opensuse Esm H88
The latest update for Fedora tackles a significant security concern regarding OpenSSL that affects RSA key creation and includes several important patches.
An update that solves one vulnerability and has 5 fixes is now available.

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.
