SUSE SLED12 / SLES12 Security Update : openssl (SUSE-SU-2018:1887-1)

Medium Nessus Plugin ID 110938

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for openssl 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)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
