Detail
Problem Description: An update for openssl is now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux BaseOS (v. 8) - aarch64, ppc64le, s390x, x86_64 3. Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library. The following packages have been upgraded to a later upstream version: openssl (1.1.1c). (BZ#1643026) Security Fix(es): * openssl: timing side channel attack in the DSA signature algorithm (CVE-2018-0734) * openssl: timing side channel attack in the ECDSA signature generation (CVE-2018-0735) * openssl: ChaCha20-Poly1305 with long nonces (CVE-2019-1543) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.1 Release Notes linked from the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. 5. Bugs fixed (https://bugzilla.redhat.com/): 1644356 - CVE-2018-0735 openssl: timing side channel attack in the ECDSA signature generation 1644364 - CVE-2018-0734 openssl: timing side channel attack in the DSA signature algorithm 1668880 - ec man page lists -modulus but the tool doesn't support it 1686058 - specifying digest for signing time-stamping responses is mandatory 1686548 - Incorrect handling of fragmented KeyUpdate messages 1695954 - CVE-2019-1543 openssl: ChaCha20-Poly1305 with long nonces 1697915 - Race/segmentation fault on process shutdown in OpenSSL 1706104 - openssl asn1parse crashes with double free or corruption (!prev) 1706915 - OpenSSL should implement continuous random test or use the kernel AF_ALG interface for random 1712023 - openssl pkcs12 uses certpbe algorithm not compliant with FIPS by default 1714245 - DSA ciphers in TLS don't work with SHA-1 signatures even in LEGACY level |
