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.","Type":"Description","Title":null},{"CveYear":"2018","CveId":"16395","Ordinal":"2","NoteData":"2018-11-16","Type":"Other","Title":"Published"},{"CveYear":"2018","CveId":"16395","Ordinal":"3","NoteData":"2020-01-15","Type":"Other","Title":"Modified"}]}}}
