Summary
Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2025-13837: When loading a plist file, the plistlib module reads data in size specified by the file itself, meaning a malicious file can cause OOM and DoS issues CVE-2025-12084: When building nested elements using xml.dom.minidom methods such as appendChild() that have a dependency on _clear_id_cache() the algorithm is quadratic. Availability can be impacted when building excessively nested documents.

Vulnerabilities 2
-
Medium 6.3
Quadratic complexity in node ID cache clearing
When building nested elements using xml.dom.minidom methods such as appendChild() that have a dependency on _clear_id_cache() the algorithm is quadratic. Availability can be impacted when building excessively nested documents.
