Description Rohit Keshri 2026-07-01 11:08:39 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.

A malicious or compromised server can make a DCMTK client using bit-preserving C-GET storage mode write files outside the chosen output directory, using both relative (../) paths and absolute paths.
