Related checks have been added at various places in order to prevent such (possible) attacks. Thanks to Kevin Basista for the report.

The bug will indeed affect all DCMTK-based server applications that accept incoming DICOM network connections that are using the dcmtk-3.6.0 and earlier versions.

(From: [link moved to references])

For Debian 7 Wheezy, these problems have been fixed in version 3.6.0-12+deb7u1.

We recommend that you upgrade your dcmtk packages.
