openSUSE Security Update : openssl-1_0_0 (openSUSE-2019-753)

medium Nessus Plugin ID 123323

Language:

Synopsis

The remote openSUSE host is missing a security update.

Description

This update for openssl-1_0_0 to 1.0.2p 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)

 - 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)

This update was imported from the SUSE:SLE-15:Update update project.

Solution

Update the affected openssl-1_0_0 packages.
