Several flaws have been found in ruby2.1, an interpreter of an object-oriented scripting language.

  • CVE-2019-15845

    Path matching might pass in File.fnmatch and File.fnmatch? due to a NUL character injection.

  • CVE-2019-16201

    A loop caused by a wrong regular expression could lead to a denial of service of a WEBrick service.

  • CVE-2019-16254

    This is the same issue as CVE-2017-17742, whose fix was not complete.

  • CVE-2019-16255

    Giving untrusted data to the first argument of Shell#[] and Shell#test might lead to a code injection vulnerability.
