An update that solves two vulnerabilities and has three
fixes is now available.
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.
