"According to the versions of the ruby packages installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :

    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-2024-27280)

    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-2024-27281)

Tenable has extracted the preceding description block directly from the EulerOS ruby security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
