high Tenable Cloud Security Plugin ID 424420

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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 3.3.2 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)

 - 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 3.3.6 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 3.3.9 has a ReDoS vulnerability when it parses an
 XML that has many digits between &# and x...; in a hex numeric character reference (&#x...;). This does
 not happen with Ruby 3.2 or later. Ruby 3.1 is the only affected maintained Ruby. The REXML gem 3.3.9 or
 later include the patch to fix the vulnerability. (CVE-2024-49761)
