openSUSE Security Update : openssl-1_1 (openSUSE-2018-1109)

Medium Nessus Plugin ID 117976

Synopsis

The remote openSUSE host is missing a security update.

Description

This update for openssl-1_1 to 1.1.0i fixes the following issues :

These security issues were fixed :

- 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

These non-security issues were fixed :

- When unlocking a pass phrase protected PEM file or PKCS#8 container, we now allow empty (zero character) pass phrases.

- Certificate time validation (X509_cmp_time) enforces stricter compliance with RFC 5280. Fractional seconds and timezone offsets are no longer allowed.

- Fixed a text canonicalisation bug in CMS

- 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_1 packages.
