Amazon Linux 2 Security Advisory: ALAS-2019-1143
Advisory Release Date: 2019-01-09 01:10 Pacific
Severity: Important
References: CVE-2018-16395 

Issue Overview:

An issue was discovered in the OpenSSL library in Ruby. 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.(CVE-2018-16395 )
