Amazon Linux 2 Security Advisory: ALAS-2024-2637
Advisory Release Date: 2024-09-12 18:30 Pacific
Advisory Updated Date: 2024-09-18 14:30 Pacific
Severity: Medium
Issue Overview:

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)
