   SUSE Security Update: Security update for openssl-1_1
______________________________________________________________________________

Announcement ID:    SUSE-SU-2018:2956-1
Rating:             moderate
References:         #1097158 #1101470 
Cross-References:   CVE-2018-0732
Affected Products:
                    SUSE Linux Enterprise Module for Basesystem 15

   An update that solves one vulnerability and has one errata
   is now available.

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)
