Description Keith Grant 2026-06-29 18:07:39 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

The qrscp application's C-STORE handler uses a specific instance from attacker-supplied DICOM datasets directly in os.path.join() without sanitization, allowing file writes to arbitrary paths.
