Test ID:1.3.6.1.4.1.25623.1.0.852086
Category:SuSE Local Security Checks
Title:SuSE Update for openssl-1_1 openSUSE-SU-2018:3013-1 (openssl-1_1)
Summary:The remote host is missing an update for the 'openssl-1_1'; package(s) announced via the openSUSE-SU-2018:3013_1 advisory.
Description:Summary:
The remote host is missing an update for the 'openssl-1_1'
package(s) announced via the openSUSE-SU-2018:3013_1 advisory.

Vulnerability Insight:
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.
