openSUSE Security Update: Security update for openssl-1_1 ______________________________________________________________________________
Announcement ID: openSUSE-SU-2018:3013-1 Rating: moderate References: #1097158 #1101470 Cross-References: CVE-2018-0732 Affected Products: openSUSE Leap 15.0 ______________________________________________________________________________
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)
This update was imported from the SUSE:SLE-15:Update update project.
