[ALAS2-2019-1143] Amazon Linux 2 2017.12 - ALAS2-2019-1143: important priority package update for ruby

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities:
CVE-2018-16395:
An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leveraged to create an illegitimate certificate that may be accepted as legitimate and then used in signing or encryption operations.
