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 3.3.2 has a DoS vulnerability when it parses an XML that     has many entity expansions with SAX2 or pull parser API. The REXML gem 3.3.3 or later include the patch to     fix the vulnerability.(CVE-2024-41946)

     REXML is an XML toolkit for Ruby. The REXML gem before 3.3.1 has some DoS vulnerabilities when it parses     an XML that has many specific characters such as ``, `0` and `%`. If you need to parse untrusted     XMLs, you many be impacted to these vulnerabilities. The REXML gem 3.3.2 or later include the patches to     fix these vulnerabilities. Users are advised to upgrade. Users unable to upgrade should avoid parsing     untrusted XML strings.(CVE-2024-39908)

    REXML is an XML toolkit for Ruby. The REXML gem before 3.3.6 has a DoS vulnerability when it parses an XML     that has many deep elements that have same local name attributes. If you need to parse untrusted XMLs with     tree parser API like REXML::Document.new, you may be impacted to this vulnerability. If you use other     parser APIs such as stream parser API and SAX2 parser API, this vulnerability is not affected. The REXML     gem 3.3.6 or later include the patch to fix the vulnerability.(CVE-2024-43398)

    REXML is an XML toolkit for Ruby. The REXML gem before 3.3.2 has some DoS vulnerabilities when it parses     an XML that has many specific characters such as whitespace character, `]` and `]`. The REXML gem     3.3.3 or later include the patches to fix these vulnerabilities.(CVE-2024-41123)
