Security update for openssl

This update for openssl fixes the following issues:

Security issues fixed:

  • CVE-2018-0734: Fixed timing vulnerability in DSA signature generation (bsc#1113652).
  • CVE-2018-5407: Fixed elliptic curve scalar multiplication timing attack defenses (bsc#1113534).
  • CVE-2018-0737: Corrected the current error detection of the current fix (bsc#1106197).
  • CVE-2016-8610: Adjusted current fix and add missing error string (bsc#1110018).
  • Add missing timing side channel patch for DSA signature generation (bsc#1113742).
  • Fixed the 'One and Done' side-channel attack on RSA (bsc#1104789).

Non-security issues fixed:

  • Added openssl(cli) so that the packages that required the openssl binary can require this instead of the new openssl meta package (bsc#1101470).

Описание

A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients.

Описание

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p).

Описание

The OpenSSL 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 recover the private key. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2b-1.0.2o).

Описание

Simultaneous Multi-threading (SMT) in processors can enable local users to exploit software vulnerable to timing attacks via a side-channel timing attack on 'port contention'.
