Rubygems.org is the Ruby community's gem hosting service. A Gem publisher can cause a Remote DoS when publishing a Gem. This is due to how Ruby reads the Manifest of Gem files when using Gem::Specification.from_yaml. from_yaml makes use of SafeYAML.load which allows YAML aliases inside the YAML-based metadata of a gem. YAML aliases allow for Denial of Service attacks with so-called `YAML-bombs` (comparable to Billion laughs attacks). This was patched. There is is no action required by users. This issue is also tracked as GHSL-2024-001 and was discovered by the GitHub security lab.

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

     REXML is an XML toolkit for Ruby. The REXML gem before 3.2.6 has a denial of service vulnerability when     it parses an XML that has many ``s in an attribute value. Those who need to parse untrusted XMLs may be     impacted to this vulnerability. The REXML gem 3.2.7 or later include the patch to fix this vulnerability.
    As a workaround, don't parse untrusted XMLs.(CVE-2024-35176)

    Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many     features to process text files and to do system management tasks (as in Perl). It is simple, straight-     forward, and extensible.(CVE-2024-27282)

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

    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.(CVE-2024-27282)
