CVSS: 9.8EPSS: 0%CPEs: 13EXPL: 0CVE-2018-16395 – ruby: OpenSSL::X509:: Name equality check does not work correctly
https://notcve.org/view.php?id=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.

https://notcve.org/view.php?id=CVE-2018-6914
Directory traversal vulnerability in the Dir.mktmpdir method in the tmpdir library in Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 might allow attackers to create arbitrary directories or files via a ..

https://notcve.org/view.php?id=CVE-2018-8778
In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure. En Ruby, en versiones anteriores a la 2.2.10, versiones 2.3.x anteriores a la 2.3.7, versiones 2.4.x anteriores a la 2.4.4, versiones 2.5.x anteriores a la 2.5.1 y la versión 2.6.0-preview1, un atacante que controla el formato de desempaquetado (similar a las vulnerabilidades de cadena de formato) puede desencadenar una sublectura de búfer en el método String#unpack. Esto resulta en una gran divulgación de información controlada. A integer underflow was found in the way String#unpack decodes the unpacking format. An attacker, able to control the unpack format, could use this flaw to disclose arbitrary parts of the application's memory. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00036.html http://www.securityfocus.com/bid/103693 http://www.securitytracker.com/id/1042004 https://access.redhat.com/errata/RHSA-2018:3729 https://access.redhat.com/errata/RHSA-2018:3730 https://access.redhat.com/errata/RHSA-2018:3731 https://access.redhat.com/errata/RHSA-2019:2028 https://lists.debian.org/debian-lts-announce/2018/04/msg00023.html https://lists.debian.org/debian-lts-announce/2018/04/msg00024.html& • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-134: Use of Externally-Controlled Format String •
