high Nessus Plugin ID 207407

Synopsis
The remote Amazon Linux 2 host is missing a security update.Description
The version of ruby installed on the remote host is prior to 2.0.0.648-36. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2637 advisory.A flaw was found in the way the Ruby REXML library parsed XML documents. Parsing a specially crafted XML document using REXML and writing parsed data back to a new XML document results in creating a document with a different structure. This issue could affect the integrity of processed data in applications using REXML that parse XML documents, write data back to XML, and re-parse them again. (CVE-2021-28965)
ruby: Arbitrary memory address read vulnerability with Regex search (CVE-2024-27282)
Tenable has extracted the preceding description block directly from the tested product security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
