    * ruby: RCE vulnerability with .rdoc_options in RDoc (CVE-2024-27281)
      * ruby: Buffer overread vulnerability in StringIO (CVE-2024-27280)
      * ruby: Arbitrary memory address read vulnerability with Regex search (CVE-2024-27282)
    CVE-2024-27280
    A buffer-overread issue was discovered in StringIO 3.0.1, as distributed in Ruby 3.0.x through 3.0.6 and
    3.1.x through 3.1.4. The ungetbyte and ungetc methods on a StringIO can read past the end of a string, and
    a subsequent call to StringIO.gets may return the memory value. 3.0.3 is the main fixed version; however,
    for Ruby 3.0 users, a fixed version is stringio 3.0.1.1, and for Ruby 3.1 users, a fixed version is
    stringio 3.0.1.2.
    CVE-2024-27281
    An issue was discovered in RDoc 6.3.3 through 6.6.2, as distributed in Ruby 3.x through 3.3.0. When
    parsing .rdoc_options (used for configuration in RDoc) as a YAML file, object injection and resultant
    remote code execution are possible because there are no restrictions on the classes that can be restored.
    (When loading the documentation cache, object injection and resultant remote code execution are also
    possible if there were a crafted cache.) The main fixed version is 6.6.3.1. For Ruby 3.0 users, a fixed
    version is rdoc 6.3.4.1. For Ruby 3.1 users, a fixed version is rdoc 6.4.1.1. For Ruby 3.2 users, a fixed
    version is rdoc 6.5.1.1.
    CVE-2024-27282
    An issue was discovered in Ruby 3.x through 3.3.0. If attacker-supplied data is provided to the Ruby regex
    compiler, it is possible to extract arbitrary heap data relative to the start of the text, including
    pointers and sensitive strings. The fixed versions are 3.0.7, 3.1.5, 3.2.4, and 3.3.1.
