From Red Hat Security Advisory 2018:0998 :
An update for openssl is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. 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.
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.
Security Fix(es) :
openssl: bn_sqrx8x_internal carry bug on x86_64 (CVE-2017-3736)
openssl: Read/write after SSL object in error state (CVE-2017-3737)
openssl: rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Additional Changes :
