openSUSE 15.0: 2018-2129-1 Moderate: OpenSSL DoS Security Fix

opensuse
Calendar Grey July 28, 2018
Scroller Opensuse
A significant enhancement for openssl-1_0_0 in openSUSE resolves a medium-level security concern and boosts the efficiency of cryptographic operations.
An update that solves one vulnerability and has two fixes is now available.

Description

This update for openssl-1_0_0 fixes the following issues:

- 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).

- Blinding enhancements for ECDSA and DSA (bsc#1097624, bsc#1098592)

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