CVE-2018-16395

Priority
Description
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.
