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)
